The laser range finder is a measurement tool that uses laser as a carrier to realize the distance measurement function. At present, the lasers used in the handheld laser rangefinders on the market mainly include the following types: semiconductor lasers with operating wavelengths of 905 nm and 1540 nm, and YAG lasers with operating wavelengths of 1064 nm. The wavelength of 1064 nanometers is harmful to human skin and eyes, especially if the eyes accidentally come into contact with 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 lāzers diapazona meklētāji, we call them "safe". For the 1064nm laser range finder, jo it ir potenciāls apdraudējumi to the human body, we call it "unsafe".
The lāzers diapazona meklētājs izmanto lāzers for distance mērījums, un the impulss lāzers stars is a monohromatisks gaisma avots ar ļoti koncentrēta enerģija. Tāpēc, kad izmantojot it, do not look tieši at the launch port, and do not use an aiming teleskops to observe the smooth reflective surface, so as not to Harm to human eyes. Be sure to measure accord to the safe operation specification in the instrument manual. Kad mērīšana in the field, do not point the launch port of the instrument directly at the sun to avoid burning out the photosensitive element of the instrument.
