11.1 Introduction of the Integration Rod
Functionality of the Integration Rod
The Integration Rod is made of fused silica and is approximately 14 centimeter long. The cross-section of the
rod has the same aspect ratio as the active surface of the DMD's used in the Light Processor. The function of
the Integration Rod is to match the shape of the light path to the shape of the DMD's and to neutralize the hot
spot effect caused by the light source.
The Integration Rod is located at the entrance of the Light Pipe. The light emitted by the light source is
reflected via the Cold Mirror into the rod, which integrates the incoming light into a homogeneous rectangle
shaped beam of light.

may never be contaminated with grease, dirt, liquid or the such. For optimal protection the rod is mounted on
an aluminium rod holder, which requires replacing together with the rod. The Integration Rod and the
aluminium rod holder together form the
