ABSTRACT:
A reflective collimator adjusts an input light beam producing an output light beam parallel to the input light beam. The input light beam is reflected and focused by a first reflector to a second reflector, then reflected from the second reflector to a third reflector, and reflected from the third reflector to a fourth reflector, and finally reflected and focused from the fourth reflector to a focus point.
