The GaAlAs semiconductor high power laser has twice the drift and fluctuation in the range readings of the 8 mW version, so it is half as accurate as the 8 mW version, but it often works in situations where the lower power laser is not sensitive enough. The laser class remains IIIB and has a wavelength of 780 nm.

The High Power Laser Option is typically designated during manufacture. Changing the laser on an existing sensor entails additional cost, as it requires significant changes and recalibration. The lifetime of the laser diode is 50,000 hours. If you need higher power than 20 mW, please contact Acuity.
