　　Laser pointer, a seemingly ordinary gadget, but you know what? They can cause damage to the camera. Let’s explore this question and how to avoid this potential risk.Even if there are obstacles to moving forward, strong laser pointer high power We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. https://highpowerlaser.shop/collections/burning-laser

　　The essence of a laser is a highly concentrated beam of light with considerable energy. Although the power of the laser pointer is relatively low, it can still cause damage to the camera’s sensor if it is directly irradiated to the camera lens.

　　Irradiating a laser beam may cause damage to the sensor or even disable the camera. In indoor or outdoor environments, there is a potential risk as long as the camera is exposed to the laser beam.

　　For a better understanding, we can analyze the effect of lasers on cameras from a scientific point of view. Lasers have a high energy density, and photons are able to generate heat on the lens and sensor. This heat can damage the sensor’s structure, leading to a decrease in image quality or even malfunction.

　　According to multiple experimental reports on the Internet, the degree of damage to the camera caused by the laser pointer is related to the intensity of the laser and the irradiation time. Generally speaking, the power of ordinary laser pointers on the market, such as the one used for presentations, is usually around 5 milliwatts, and it will not cause much damage to the camera in a short time.

　　But if it’s a higher-powered laser pointer, such as a 3B-like laser, they generate enough heat to damage the camera after a long period of exposure.

　　So, if you accidentally shine a laser pointer on the camera, don’t worry too much, a brief contact is unlikely to cause permanent damage. But to be on the safe side, try to avoid this as much as possible.

　　However, this doesn’t mean that all cameras will be affected to the same extent. The material, design, and manufacturing quality of a sensor can affect its resistance to lasers. For example, some surveillance cameras may be equipped with special lenses or filters that are used to attenuate the effects of the laser beam, reducing the risk of damage.

　　To protect your camera, there are a few simple precautions you can take.

　　First of all, when using the laser pointer yourself, try to avoid shining the beam directly on the phone camera. Secondly, if you notice someone using a laser pointer (the same is true for spotlights on stage and concerts), especially near the camera, put away your phone in time and stop shooting directly to avoid potential dangers. Finally, when not using your phone, use a phone case or cover to protect the camera lens from the laser beam.

　　In practice, although laser pointers may have some impact on the camera, taking proper precautions and using them with caution can effectively reduce the potential risk of damage.

　　The above is an analysis of the damage that a laser pointer can cause to the camera. Do you understand? Feel free to leave a message in the comment area.

　　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.

　　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.

　　Laser pointer, also known as laser pointer, pointer, etc., is a pen-shaped emitter designed to be portable, easy to hold in the hand, and processed into a laser module (diode). Common laser pointers include red (650-660nm), green (532nm), blue (445-450nm), and blue-violet (405nm). It is usually used by newspapers, teachers, and docents to project a point of light or a ray of light directed at an object.If we can practice these points, burning laser pointer Will be unique, become a leader in the industry, and keep moving forward. https://highpowerlaser.shop/collections/burning-laser

　　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.
