11. INTEGRATION ROD

About this chapter
This chapter describes briefly the functionality of the integration rod, how to diagnose the integration rod, how to replace this rod
and how to adjust it.
Functionality
The integration rod is made of fused silica and is approximately 13 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. Futhermore, the integration rod
ensures that the light beam is focused on the DMD's, which results in an optimally focused light beam on the screen.
The integration rod is located at the entrance of the light pipe. The light emitted by the lamp is reflected via the "cold mirror" into the
rod, which integrates the incoming light into a homogeneous rectangle shaped beam of light.

The entrance and exit side of the integration rod are coated to achieve optimal performance. Clearly the rod may never be contam-
inated with grease, dirt, liquid or the such. for optimal protection the rod is mounted inside an aluminium tube, which has requires
replacing together with the rod. This aluminum tube also contains an adjustment mechanism to position the rod inside the light pipe.
The integration rod, the aluminium tube and the adjustment mechanism together form the "integration rod assembly".
