10.1 Introduction Light Pipe
Light Pipe
The Light Pipe transforms the light emitted by the light source into a homogeneous light beam and focuses
this beam precisely on the active surface of the DMD
’ s. The Light Pipe is mounted onto the Corner Block.
The Light Pipe itself contains the Integration Rod at the Light Pipe entrance, the Light Pipe lenses No1-2-3,
the Notch Filter, and the High Contrast Plate. The Light Pipe can easily be removed from the Corner Block for
servicing.
The Corner Block contains the Fold Mirrors which are folding up the light path of the projector to make the
projector more compact, the Light Pipe lens No4, and the Light Sensor Module which ensures a Constant
Light Output (CLO) of the projector. Note that the Light Processor and Lens Holder are directly mounted onto
the Corner Block. This ensures a precise mounting with minimum tolerance of all optical components in the
light path which results in perfect optical performance.
