Do you need longer range or longer battery life for your LRF? Changing a diode delivers both.
Professional laser range finders (LRFs) usually adopt 1550 nm as the wavelength of the light pulses used for their operation. The main alternative, 905 nm, suffers from severe eye-safety pulse energy limitations. This is due to the low divergence point source needed to keep power on the intended target. It means that the advertised range of 905 nm systems is often only achieved on larger extended targets, which limits their effectiveness. 905 nm light is also visible through night vision goggles that have image intensifiers, which makes systems that use it unsuitable for defence applications and more commonplace in consumer products.
The laser diodes that generate the light pulses are the dominant consumers of battery power and a key determinant of the instruments’ range. …
