As the name implies, the laser rangefinder is a measurement tool that uses laser as a carrier to achieve distance measurement. At present, the lasers used in the handheld laser rangefinders on the market mainly include the following types: semiconductor lasers with a working wavelength of 905 nm and 1540 nm, and YAG lasers with a working wavelength of 1064 nm. The wavelength of 1064 nanometers is harmful to human skin and eyes, especially if the eyes are accidentally exposed to the laser with a wavelength of 1064 nanometers, the damage to the eyes may be permanent. Therefore, in foreign countries, the 1064 nanometer laser is completely banned in the handheld laser rangefinder. In China, some manufacturers also produce 1064nm laser rangefinders.
For 905nm and 1540nm laser rangefinders, we call them "safe". For the 1064nm laser range finder, क्योंकि it has पोटेंशियल खतरे to the human body, we call it "असुरक्षित".
