What's so special about the laser of the laser rangefinder?
The laser rangefinder, as its name suggests, is a measurement device that measures distance using a laser as a carrier. YAG lasers with operating wavelengths of 1064 nm and semiconductor lasers with operating wavelengths of 905 nm and 1540 nm are the two most common types of lasers now employed in handheld laser rangefinders available on the market. In particular, if the eyes mistakenly come into contact with a laser with a wavelength of 1064 nanometers, the damage to the eyes could be irreversible. The wavelength of 1064 nanometers is hazardous to human skin and eyes. Therefore, the 1064 nanometer laser in handheld laser rangefinders is entirely outlawed in other nations. Some producers of 1064nm laser rangefinders are based in China.
We refer to the 905nm and 1540nm laser rangefinders as "safe." We refer to the 1064nm laser range finder as "unsafe" since there may be risks to the human body.
The pulsed laser beam from the laser rangefinder is a monochromatic light source with extremely concentrated energy, and it is used to measure distance. So as not to harm human eyes, when using it, avoid looking directly at the launch port and avoid using an aiming telescope to see the smooth reflective surface. Make careful you measure in accordance with the instrument's manual's safe operation guidelines. Avoid aiming the instrument's launch port directly towards the sun when taking measurements outside to prevent damaging the instrument's photosensitive component.
