Laser rangefinder: laser safety warnings and precautions for use Lasers are high-intensity light source radiation devices. High-power lasers can be used to cut and weld metal materials. Therefore, lasers can cause serious damage to the human body, especially the human eye. Be especially careful.

There are unified classification and unified safety warning signs for lasers in the world. Lasers are divided into four categories (Class1~Class4). Class 1 lasers are safe for people, class 2 lasers cause less harm to people, and lasers of class 3 and above are safe for people. Lasers can cause serious harm to people, so special attention should be paid to avoid direct exposure to human eyes.

Laser rangefinder: In the early 1990s, several major companies in Europe and the United States successively produced semiconductor laser diodes for commercial use, which revolutionized the practical application value of lasers. Due to the complicated mechanism of laser generation, other types of lasers have a particularly large volume, weight, and high power consumption, which greatly limit the application of lasers. The emergence of semiconductor lasers has solved these problems. As the technology of semiconductor lasers becomes more mature, the price gradually decreases, and its application batch and application fields continue to expand. Judging from the current development speed, the application prospects are very promising. Semiconductor lasers are small in size, light in weight, high in reliability, high in conversion efficiency, low in power consumption, simple in driving power, can be directly modulated, simple in structure, low in price, safe to use, and have a wide range of applications. Such as optical storage, laser printing, laser phototypesetting, laser ranging, bar code scanning, industrial detection, testing and measuring instruments, laser display, medical equipment, military, security, field detection, construction leveling and marking instruments, laboratories and teaching Demonstration, stage lighting and laser performance, laser level and various marking positioning, etc. Some unique advantages of semiconductor lasers make them very suitable for military applications, such as field ranging, aiming of guns, shooting simulation systems, blinding, submarine communication guidance, fuzes, security, etc. Since it can be powered by ordinary batteries, some portable weapon equipment configurations are possible.

Laser rangefinder: The wavelength bands of semiconductor lasers that have been developed and put on the market are 370nm, 390nm, 405nm, 430nm, 480nm, 635nm, 650nm, 670nm, 780nm, 808nm, 850nm, 980nm, 1310nm, 1550nm, etc., of which 1310nm, 1550nm is mainly used in the field of optical fiber communication. 405nm-670nm is the visible light band, 780nm-1550nm is the infrared light band, and 390nm-370nm is the ultraviolet light band. High-tech products and professional technology lead the trend of ranging industry. The advantages of many types, complete varieties, high precision, and easy portability are more convenient for users to choose and use. Meet the needs of various industries!
