A new far infrared detector

We have constructed a far infrared bolometer detector by using a single crystal chip of p-type undoped thallium selenide as the temperature sensitive element. The bolometer operates at 1.6°K and achieves a noise equivalent power of 8.3 × 10 −15 W/√Hz with a time constant of 22 msec. The measured res...

Description
Summary:We have constructed a far infrared bolometer detector by using a single crystal chip of p-type undoped thallium selenide as the temperature sensitive element. The bolometer operates at 1.6°K and achieves a noise equivalent power of 8.3 × 10 −15 W/√Hz with a time constant of 22 msec. The measured responsivity is 6 × 10 5 V/W. The detector should be suitable for infrared and microwave applications.
