Peltier Cooling for Noise Reduction

|
By active cooling with peltier elements the dark noise of the sensors can be lowered significant. So even superior applications can use more inexpensive sensors.
The following table lists the most often used peltier elements for the cooling of linear and area sensors:

Beside the pure peltier elements for cooling CCD/CMOS sensors, we offer also a wide supply of accessories as e.g. thermal conductive adhesives, heat sinks and fans. On request we offer further the development of complete cooling applications.
