How to use the laser rangefinder correctly?
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, so lasers have serious damage to the human body, especially human eyes, and special care must be taken when using them.
Internationally, there is a unified classification and unified safety warning signs for lasers. Lasers are divided into four categories (Class1~Class4). Class I lasers are safe for humans, Class II lasers cause minor harm to humans, and lasers of Class III or above are safe for humans. Lasers can cause serious harm to people, so special attention should be paid when using them to avoid direct exposure to human eyes.
In the early 1990s, several major companies in Europe and the United States successively produced commercially available semiconductor laser diodes, which greatly improved the practical application value of lasers. For other types of lasers, due to the complex mechanism of laser generation, the volume, weight are particularly large, and the power consumption is high, which greatly limits the application of lasers. The emergence of semiconductor lasers has solved these problems. With the further maturity of semiconductor laser technology, the price gradually decreases, and its application volume and application field continue to expand. Judging from the current development speed, the application prospect is 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, capable of direct modulation, simple in structure, low in price, safe in use, and have a wide range of applications. Such as optical storage, laser printing, laser phototypesetting, laser ranging, barcode scanning, industrial detection, test and measurement instruments, laser display, medical equipment, military, security, field detection, construction leveling and marking instruments, laboratories and teaching Demonstration, stage lighting and laser show, laser level and various marking positioning, etc. Some unique advantages of semiconductor lasers make them very suitable for safety applications, such as field distance measurement, gun aiming, shooting simulation systems, blinding, submarine communication guidance, fuze, security, etc. Since it can be driven by ordinary batteries, some portable weapon equipment configurations are possible.
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 and 1550nm are mainly used for optical fibers communication field. 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, professional technology and safe ranging industry trend. Many types, complete varieties, high precision, easy to carry and other advantages are more convenient for users to choose and use. Meet the needs of various industries!
