8.1 Description of the optical path
Description
The light beam coming from the Xenon lamp is aligned and focussed by lenses and mirrors to fall onto the DMD in a uniform way.
The white beam is spit into three colors (red, green, blue): each of the colors is directed to one single DMD. The projector lens is
used to come to a focussed image on the screen.
