Abstract
An improved laser projector collimator includes a plurality of specifically designed and arranged mirrors and lenses such that reflected light from a housing window for the laser projector is not directed onto a reflected light source sensor. In this way, the sensor only sees light reflected from a reference reflector. In addition, the specific arrangement of the lenses and mirrors is such that the overall length of the collimator housing is greatly reduced.
