Introduction HDF Cold Mirror
Functionality of the Cold Mirror
The location of the Cold Mirror in the light path is between the light source (xenon lamp) and the light pipe. The Cold Mirror re
fl
ects
the visible light and absorbs the infra red light. Due to this absorbing, a lot of heat is produced. The rear side of the Cold Mirror is
equipped with a cooling assembly (heat sink + fan). The fan below the heat sink blows cold air on the Cold Mirror and heat sink.
The Cold Mirror has two adjustment screws to modify the position of the Cold Mirror so that the centre of the light spot is precisely
re
fl
ected in the centre of the Integration Rod entrance for optimal performance.

Diagnostic
The easiest way to check the condition of the Cold Mirror is by removing the Lamp House. When the Lamp House is removed, the
Cold Mirror becomes visible at the end of the lamp house compartment. In case the Cold Mirror is not damaged but dirt is clearly
visible upon the surface of the mirror it is recommended to clean the Cold Mirror. Always replace the Cold Mirror with a new one in
case the Cold Mirror is damaged. Possible damages are:
•
Cold Mirror is broken.
•
Coating peels off.
•
Cold Mirror is cracked.
The light output on the screen will be lower than the normal light output in case of a damaged or dirty Cold
Mirror.
