Patent ID: 6892030

Claim:
A system for effecting temperature control in a camera, comprising: a camera housing having a window portion through which radiation from a scene external to the camera housing can enter the camera housing and travel within the camera housing along a path of travel; a lens housing having an optical stop disposed within the camera housing, the optical stop having an aperture formed therein that is associated with the path of travel; a lens disposed within the lens housing, the lens having a forward surface adjacent an aft surface of the optical stop, the forward surface having an annular portion and a polished portion inside the annular portion that is adapted to receive the radiation through the aperture; and a thermally conductive material disposed between and engaging both the annular portion of the lens and the aft surface of the optical stop, the thermally conductive material having a thermal conductivity of at least approximately 1.90 W/m·K.
