How to use laser rangefinder correctly

Laser Safety Warnings and Precautions Lasers are high-intensity light source radiating devices. High-power lasers can be used to cut and weld metal materials. Therefore, lasers are seriously harmful to the human body, especially the human eye. Special care must be taken when using them.

Internationally, there is a unified classification and uniform safety warning signs for lasers. The lasers are divided into four categories (Class1 to Class4). One type of laser is safe for humans, the second type of laser has lighter damage for people, and three types of lasers. The laser is seriously harmful to people, and special care should be taken when using it to avoid direct exposure to the human eye.
In the early 1990s, several major companies, such as Europe and the United States, successively produced semiconductor laser diodes for commercial use, which revolutionized the practical application value of lasers. Other types of lasers have greatly limited the application of lasers due to the complexity of the mechanism for generating lasers, their volume, weight, and power consumption. The emergence of semiconductor lasers has solved these problems. As the technology of semiconductor lasers is further matured, prices are gradually reduced, and its application volume and application fields are expanding. As far as the current development speed is concerned, the application prospects are very promising. The semiconductor laser has small volume, light weight, high reliability, high conversion efficiency, low power consumption, simple driving power supply, direct modulation, simple structure, low price, safe use, and wide application fields. Such as optical storage, laser printing, laser phototypesetting, laser ranging, bar code scanning, industrial detection, test and measurement instruments, laser display, medical instruments, military, security, field detection, construction leveling and marking instruments, laboratory and teaching Demonstration, stage lighting and laser show, laser level and various markings. Some of the unique advantages of semiconductor lasers make them ideal for military applications such as field ranging, gun sighting, shooting simulation systems, blinding, submarine communication guidance, fuzes, security, and more. Some portable weapon device configurations are possible because they can be driven by ordinary batteries.

The wavelengths of semiconductor lasers that have been developed and put on the market are 370 nm, 390 nm, 405 nm, 430 nm, 480 nm, 635 nm, 650 nm, 670 nm, 780 nm, 808 nm, 850 nm, 980 nm, 1310 nm, 1550 nm, etc., of which 1310 nm and 1550 nm 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 and professional technology lead the trend of the distance measurement industry. The variety, variety, high precision, easy to carry and other advantages are more convenient for the majority of users to choose and use. Meet the needs of various industries!
