Cooled PbSe infrared photoconductive detectors
Assembling of PbSe photo detectors on single or dual phase Peltier thermoelectro coolers
(TECs) gives the opportunity to improve the stability of instruments, applied those detectors,
in wide temperature range. It is also increase it's sensitivity.
Cooled photoresistors are basic manufactured in house TO-8 with windows from AR coated silicon or
IR quartz. Optionally we are manufacturing two-element photoresistors, assembled together on one
TEC both with assembled individual interference filters.
Typical operation conditions of photo detectors assembled on different types of TECs are the
- Ambient temperature: +25oC
- Operating temperature of photo detector: -25oC
- Typical requirements for power supply of TEC's models at maximum cooling:
TEC model 1MS-06-018: 2,2 V@ 1,5 A
TEC model 1MS-04-032: 4,0 V@ 0,4 A
