However, there are not only a variety of styles that compound the functions of the briefing machine and mouse in the laser pointer products, but also common red light and professional-grade green light and blue light in terms of light color, so it must not be easy to buy.Under people’s attention powerful laser Finally grow into what people need, born for the market and come for the demand. https://highpowerlaser.shop/collections

　　Therefore, this article will take you to understand the purchase skills of laser pointers, whether you want to find a style for presentations, or need a higher power industrial laser pointer, as long as you can find the most suitable product after reading this article, let’s read down to take a look!

　　Benefits of using a laser pointer:

　　When teaching and giving presentations on the podium, it is usually necessary to use auxiliary props such as laser pointers, so that the audience can clearly know where the content mentioned is on the PPT. However, many people who are looking for convenience and speed will choose to use their hands or long instruments such as batons to instruct, but laser pointers also have many irreplaceable advantages.

　　First, when the screen is too large or inconvenient to move around on stage, the hand and stylus may not be able to reach every corner of the frame, while the laser pointer can easily reach all the beams. In addition, when using a finger or a command pen, it is inevitable that part of the picture will be obscured by the shadow of the body, and the dotted laser pointer ensures that the audience can see the full text and graphics of the presentation.

　　In addition, when using a projector or or other device to make a report, it is common to turn off light sources such as electric lights to make the projected image clearer, but at the same time, the narrator’s movements become difficult to read due to the darkness, and the laser pointer can be clearly seen in a dimly lit environment. Therefore, it is recommended that all commentators buy a laser pointer in case of emergency, which will not only be more flexible in the way of use, but also greatly improve the accuracy of the report.

　　Key points for choosing a laser pointer

　　Next, we will explain what to consider when choosing a laser pointer, and whether you are buying from a physical store or an online store, you can find a product that meets your needs by checking the following points.

　　1. Think about the color of the light first

　　Laser pointers are mainly divided into red and green depending on the wavelength of the light, and although there are other colors such as blue light on the market, the following details the differences between the most common red and green colors.

　　1.1 Red light: high popularity, relatively affordable and easy to get

　　The red light type must be the most familiar laser pointer style in everyone’s impression, because of its cheapness, many styles and high popularity, it is very suitable for people who want to start quickly, in addition, the red light type due to low power consumption, a single battery can be used for a long time and is not easy to cut off, it is quite recommended to use people with high frequency to buy.

　　However, compared with green light, red light is not easy to project on screens such as plasma TVs, and its visual sensitivity and irradiation distance are also unsatisfactory, but it is more than enough for use in small spaces in classrooms or conference rooms.

　　1.2 Green light: suitable for large, bright spaces

　　Green light has high visual sensitivity and a long projection distance, and there are even high-performance models with a range of up to 200~300m on the market, so it is more stable for people who often use it in large conference rooms and lecture halls. However, due to the complexity of the structure, the average price is higher than that of the red light model; However, if you buy a cheap model, problems such as unstable beam output may occur, so it is recommended to compare the performance of each product when buying a green laser pointer to avoid mistakes.

　　2. The shape affects the feel when using

　　Laser pointers have a variety of styles to choose from depending on the shape, and it is recommended to evaluate the suitable products according to personal usage habits. For example, users who prioritize portability can choose a small pen type or key ring type; If you are concerned about the freedom of your hands when using it, you can choose a ring that can be fastened to your finger like a ring; For those who value grip, there is a special shape that enlarges the grip to match the shape of the palm.

　　However, when considering the feel, we should not ignore the disadvantages that come with it, such as the light source of the ring model is usually weak, and the style with a large grip will be bulky overall, so it is important to evaluate the balance of the advantages and disadvantages of the product when purchasing in order to find the most ideal product.

　　3. Diverse accessibility features

　　In addition to the models that simply have the function of an indicator light, there are also models with a variety of wireless technologies that can improve the smoothness of reporting.

　　3.1 Presentation function: easily switch PPT pages

　　Many occasions that use laser pointers to report will be operated together with PowerPoint (referred to as PPT) and other presentation software, at this time, if you choose a model with wireless technology, you can freely turn the page, so that the process of reporting can be more easily explained and freely interact with the audience without the scope of the computer.

　　3.2 Mouse function: free operation of the computer

　　If you have to operate the computer to play videos and open Excel spreadsheets from time to time, it is recommended to choose a laser pointer with mouse function, because it can freely click and slide the page, which can greatly reduce the rhythm of the report caused by operating the computer. Although this type of product has a large number of buttons and takes time to get started, it can be a great tool for presentations after getting used to the interface.

　　4. Confirm the range of wireless signal reception

　　If you intend to use the additional functions described in the preceding paragraph, the signal is usually connected by a USB wireless receiver or Bluetooth, and in order to ensure a smooth and uninterrupted signal between the laser pointer and the computer, it is important to confirm the signal reception range of the product when purchasing the relevant product.

　　Most of the signal range in commercial products falls between 10m~30m, so if you plan to use it in a large conference room, it is recommended to choose a wide range of models. In addition, the Bluetooth model usually has a large signal reception range, and even a long-distance product of up to 50m can be found, if you can’t confirm the size of the site before arriving at the site, or often operate the laser pointer in different scale locations, you must be able to use the Bluetooth laser pointer more securely.

　　5. CNS mark: to ensure product safety

　　Since the laser pointer is made to be recognized by the human eye by projecting a high-power concentrated beam, if it is directly irradiated to the eye, there will be a risk of blindness, so it is important to choose a model that has been inspected by the Bureau of Standards, Inspection and Inspection of the Ministry of Economic Affairs and passed the national standard (CNS, also known as orthography) when purchasing.

　　Generally speaking, the power of laser pointers for presentation on the market is limited to laser class 2 and 1mW, but if it is used for advanced applications such as engineering and stargazing, there are also products with higher power on the market, so it is recommended to select products according to individual use purposes. If you only need to use it in small spaces such as classrooms and conference rooms, you can reduce the risk to humans by choosing products with safety signs.

　　summary

　　In order to complete a perfect briefing, a laser pointer that can make a point is indispensable. By reading the key points of this article, I believe you have gradually clarified what products are suitable for you. I wish everyone can choose the right laser pointer for you.

　　A physical picture of a common laser pointer

　　Early laser pointers (HeNe) HeNe gas lasers produce a laser wavelength of 633nm, typically 1mW. The cheapest laser pointers use a deep red laser diode with a wavelength of nearly 670/650nm. Slightly more expensive with red, orange 635nm diodes. Other colors are also possible, with the green laser at 532 nm being the most common alternative. Later, an orange-yellow laser pointer with a wavelength of 593.5 nm appeared. In 2005, a 473nm blue laser pointer appeared, which was introduced in September. At the beginning of 2010, a blue-violet laser pointer with a wavelength of 405 nm appeared.

　　The brightness of the laser beam on the spot depends on the laser power, the reflectivity of the surface. For the same power, the spectrum of the human eye in the green region (wavelength 520-570nm) is most sensitive and appears to be brighter than other colors. The sensitivity of the wavelength of red or blue decreases.

　　A laser pointer that typically represents the output power of milliwatts (mW). In the United States, lasers are classified by the National Standards Institute and the Food and Drug Administration (FDA). Visible laser pointers (400-700nm) operate at less than 1mW of power, Class 2 or II, visible 1-5mW laser pointers, are Class 3A or IIIa. Class 3B or IIIb lasers produce 5 to 500 mW; Class 4 or 4 lasers produce more than 500mW. The U.S. FDA regulations state that “demonstration laser products” must meet applicable requirements for Class I, IIA, or IIIA devices.

　　Measured laser map

　　Red and orange laser pointers

　　This is the simplest laser because there are red diodes. No more than one battery-powered laser diode. The first red laser pointer, released in the early 80s of the 20th century, sold for a few hundred dollars. Today, they are much smaller and generally cost very little. Diode-pumped solid-state (DPSS) red lasers at 671nm are common.

　　Yellow laser pointer

　　Yellow laser pointers are extremely rare in the market. DPSS technology is obtained by adding two laser beams with wavelengths of 1064 nm and 1342 nm through a nonlinear crystal. The complexity of the process makes the yellow laser pointer unstable and inefficient, with an output power of 1-10mW depending on the temperature, and a pattern jump if it is overheated or too cold. This is because the size of the laser pointer does not provide the required temperature stabilization and cooling parts. In addition, most 593.5nm laser pointers operate in pulsed mode to allow for the use of pump diodes with smaller size and power.

　　Green laser pointer

　　The nonlinear crystal is excited by an infrared laser with a wavelength of 808nm to produce 1064nm infrared light, and then 532nm green light is generated by frequency doubling, which belongs to solid-state lasers. Some green lasers operate in pulsed or quasi-continuous mode to reduce cooling problems and extend battery life. Green lasers, which do not require frequency doubling, have higher efficiency. At night, even low-power green light can be seen due to Rayleigh scattering of atmospheric molecules, and this laser pointer is often used by astronomy enthusiasts to point to stars and constellations. Green laser pointers can have a variety of output powers. The 5mW (IIIA) is the safest to use and is also visible in dim lighting, so no more power is required for pointing purposes.

　　Blue light laser pointer

　　Blue laser pointers such as a specific wavelength of 473 nm usually have the same infrastructure as green lasers. Many factories in 2006 began to produce blue laser modules, mass storage devices, these used laser pointers. This is the type of equipment that pumps the frequency doubling with semiconductors. They most often emit 473 nm, which is doubled by a frequency multiplied by a diode-pumped laser at 946 nm ND:YAG laser or yttrium neodymium vanadate crystals. The BBO crystal with high output power is used for KTP crystals as a lower power doubling.

　　Visible wavelength green laser pointer

　　Some manufacturers are selling indicators of parallel blue laser diodes measuring power over 1500 milliwatts. However, since the claimed power of the “laser pointer” product also includes infrared power (only in semiconductor pumping technology) is still in the beam (for reasons discussed below), the laser is still problematic on the basis of the DPSS-type elements of the more strict visual blue, and is usually not applicable. Due to the use of higher neodymium harmonics, the frequency doubling conversion efficiency is low, and the infrared power is a small fraction of the optimal configuration of the semiconductor pump module, and the conversion of a blue laser at 473 nm is typically 10-13%, which is about half of that typical of green lasers (20-30%).

　　The blue laser can also directly fabricate indium gallium nitride semiconductors, producing frequency-grabby blue light. There are blue laser diodes on the market (447＼5 nm), and the device is a bright same violet laser diode with a power of less than 405 nm, because the longer wavelength is closer to the peak sensitivity of the human eye. The mass production of laser projectors for commercial equipment, such as laser diodes, has driven down prices. The use of popular high-power (1W) 447 nm indicators, which also have improved optical versions of better collimation and lower divergence, comparable to the use of these portable devices, has reduced the sensitivity of green lasers with the intention and cost of human harm.

　　Why should even the medals and badges be customized? This is a problem that many people don’t understand. In fact, in our life, no matter in schools or enterprises, we will encounter all kinds of competitions, and each competition will inevitably have different awards. Apart from some realistic material rewards, medals, trophies or badges are also essential.In addition to these aspects, design your own custom badge The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://www.karonmetal.com

　　Customized medals, trophies and badges represent a sense of ceremony given by the organizers and a sense of honor given by the contestants themselves. Then what should we pay attention to when customizing medals and badges as demanders?

　　First, the medal badge style

　　When customizing the design style of medals and badges, it is necessary to integrate the design style that the customization party wants based on the purpose of the product and the inheritance of corporate culture and the spirit of events. At the same time, it is necessary to customize different types of products according to different scenes, and determine the size, proportion, coordination, appropriateness and standard of medal badge products.

　　II. Contents of medals and badges

　　Generally, the customized surface content of the medal badge is the company (school or organization) abbreviation, logo, theme and other information, so it is forbidden that too much information leads to the accumulation of words on the surface of the medal badge. As simple as possible, accurately and completely express the purpose of making medal badges.

　　Third, the medal badge technology

　　Because the materials for making medals and badges are different, the manufacturing process is also diverse. For example, the production of metal medals can be made into colorful and exquisite medals through baking paint and enamel processing, which has a strong three-dimensional effect and various patterns are prominent. Soft enamel and resin are used as coloring materials, and the surface can be plated with gold, nickel and other metal colors, which are smooth and delicate, giving people a very noble feeling.

　　Fourth, medal badge materials

　　The materials for making customized medals and badges need to be determined according to the needs of the customization party. Compared with precious metals, gold, silver and ordinary metals, the precious materials of gold, silver and precious metals are more expensive. The customization party can decide whether the medals are high-grade or not and what materials to choose according to the requirements of different scenes.

　　V. Details of medals and badges

　　The details of customizing the medal badge mainly show whether the font selection is appropriate when customizing the medal badge, and what style of medal wooden support and medal ribbon are selected to match the medal badge; The thickness of medal badge, the width of hem and edge, the plane arch surface, etc., are considered according to different customization requirements.

　　In today’s modern electrical systems, ensuring signal integrity and preventing electromagnetic interference (EMI) are critical for the smooth operation of sensitive devices. This is where multicore shielded cables come into play. These cables are designed with multiple cores of insulated conductors wrapped in a protective shield that helps block external electromagnetic interference. Whether you¨re dealing with multicore shielded cables for robotics or industrial machinery, understanding how these cables prevent interference is key to optimizing your systems.period EV cable manufacturing Many adjustments have also been made, and the direction of product research and development has been reversed, in order to better meet the market demand. https://www.linkcablecn.com

　　What Are Multicore Shielded Cables?

　　Multicore shielded cables are specialized cables with several internal conductive cores, each typically insulated to prevent short circuits. The key feature of these cables is their protective shield, often made from materials like copper, aluminum, or braided wire, which surrounds the cores. This shield serves as a barrier against external electrical noise and interference, ensuring the integrity of the transmitted signal.The core structure of the cable allows for multiple signals to be transmitted through a single cable, which makes them ideal for a range of applications, from power distribution to data transfer. In environments where noise and signal degradation can compromise system performance, multicore shielded cables offer a reliable solution.

　　How Do Multicore Shielded Cables Prevent Interference?

　　Electromagnetic Interference (EMI) Shielding:The primary function of the shield in multicore shielded cables is to protect against electromagnetic interference (EMI). EMI is caused by electrical signals that radiate from power lines, machinery, or other devices. These signals can disrupt sensitive equipment, causing data loss, equipment malfunction, or even system failure. The shield in shielded multicore cables acts as a barrier, absorbing and deflecting these unwanted electromagnetic waves, ensuring that the transmitted signals remain unaffected by external interference.

　　Grounding the Shield:In many multicore shielded cables, the shield is grounded to divert the interference away from the sensitive conductors inside the cable. This grounding method helps direct the EMI to a safe location, typically back to the ground, where it cannot affect the system. The grounding further enhances the ability of the cable to maintain signal integrity and avoid signal degradation caused by external noise.

　　Prevention of Crosstalk:In cables with multiple cores, especially those used in multicore shielded cables for robotics and other industrial systems, the risk of crosstalk！where signals from one core interfere with others！can be high. The shielding not only prevents external interference but also helps reduce crosstalk between the cores themselves. This ensures that each signal remains clear and free from distortion, which is especially important in complex systems that rely on precise data transfer.

　　Flexibility and Durability:Flexible multicore shielded cables offer an added benefit in environments where cables need to be moved or bent regularly. The flexibility of these cables doesn¨t compromise their ability to block interference. These cables maintain their shielding effectiveness even under bending or twisting, making them ideal for robotics, manufacturing, and other dynamic applications where movement is common.

　　Improved Signal Quality Over Long Distances:One of the main advantages of shielded multicore cables is their ability to maintain high-quality signal transmission over long distances. Without proper shielding, cables can suffer from signal degradation due to the interference picked up over the distance. The shielded design of these cables minimizes the risk of signal loss, making them an excellent choice for applications requiring long cable runs, such as in industrial settings, robotics, or data centers.

　　Grounding the Shield:In many multicore shielded cables, the shield is grounded to divert the interference away from the sensitive conductors inside the cable. This grounding method helps direct the EMI to a safe location, typically back to the ground, where it cannot affect the system. The grounding further enhances the ability of the cable to maintain signal integrity and avoid signal degradation caused by external noise.

　　Prevention of Crosstalk:In cables with multiple cores, especially those used in multicore shielded cables for robotics and other industrial systems, the risk of crosstalk！where signals from one core interfere with others！can be high. The shielding not only prevents external interference but also helps reduce crosstalk between the cores themselves. This ensures that each signal remains clear and free from distortion, which is especially important in complex systems that rely on precise data transfer.

　　Flexibility and Durability:Flexible multicore shielded cables offer an added benefit in environments where cables need to be moved or bent regularly. The flexibility of these cables doesn¨t compromise their ability to block interference. These cables maintain their shielding effectiveness even under bending or twisting, making them ideal for robotics, manufacturing, and other dynamic applications where movement is common.

　　Improved Signal Quality Over Long Distances:One of the main advantages of shielded multicore cables is their ability to maintain high-quality signal transmission over long distances. Without proper shielding, cables can suffer from signal degradation due to the interference picked up over the distance. The shielded design of these cables minimizes the risk of signal loss, making them an excellent choice for applications requiring long cable runs, such as in industrial settings, robotics, or data centers.
