8. Light processor assembly
8.1 Introduction
Light Processor assembly
The light processor as sem bly has three major s ub assemblies, namely: the Light Processor Unit (reference 1 ) with dowser (reference
2) and the Light Pipe assembly (reference 3).

Light Pipe
The Light Pipe transforms the light emitted by the lamp into a homogeneous light beam and focuse s this beam precisely on t he active
surface of the DMD’s. The Light Pipe contains the Integration Rod at the Light Pipe entrance, the Light Pipe focus and rotation knobs
which matches the s ize of the light beam with the size of the DMD’s, the Folding M irror which folding up the light path of the projector
to make the projector m ore compact, and the Light Sensor Module w hich en sures a Constant Light Output ( CLO) of the projector.
Furthermore, the Light Pipe has a Notch fi lte r on the exit which applies some small color corrections on the light coming out of the
Light Pipe.

Light Processor
The Light Processor is the heart of the projector. The p rism of the Light Pr ocessor splits up the hom ogeneous white light coming
from the Light Pipe into r ed, green and blue light. The video information o n t he three D MD ’s is integrated with these red gr een and
