The thermoregulating block of cooling of a photovoltaic detectors

 

The thermoregulating block of cooling of a photovoltaic detectors

It is intended for noise reduction of photovoltaic detectors . Its application allows to increase the relation "signal/ noise" more than by one order.

It is applied for cooling of photodiodes such as a InAsSb and photoresistors such as a PbS, PbSe.
