摘要： A camera system exhibiting reduced effects from temperature changes. The camera system includes an IR sensor; an optical arrangement adapted to focus incoming light onto the sensor; a processing arrangement adapted to process signals produced by the sensor; a heatsink in thermal contact with and is adapted to transfer heat energy away from, the processing arrangement; and a thermal equalizer. The thermal equalizer at least partially surrounds and is in thermal contact with the optics/sensor unit and is formed at least partially from a material having a high thermal conductivity. The thermal equalizer conducts heat energy from warmer to cooler parts of the optics/sensor unit. The thermal equalizer is also thermally insulated from ambient air surrounding the camera system and from the heatsink.
