Cryogenic Associates IR-12M dewar detector

Product Description

Cryogenic Associates IR-12M Infrared Dewar Detector Assembly

This is a complete cryogenically cooled infrared detector system, designed for high-sensitivity measurements in spectroscopy, thermal imaging, or research applications. The integrated dewar allows for liquid nitrogen (LN2) cooling of the sensor element, typically an InSb or HgCdTE detector, to reduce noise and maximize performance in the mid-wave (MWIR) or long-wave (LWIR) infrared bands.

Key Components & Specifications:

• Model: IR-12M

• Detector Type: Likely InSb (3–5 µm) or HgCdTe (8–12 µm)

• Cooling Method: Liquid Nitrogen (LN2) Dewar – metal vacuum-jacketed flask

• Window Material: Germanium, zinc selenide, or similar IR-transmitting material

• Electrical Connection: Likely includes a multi-pin connector for bias and signal output

• Hold Time: Typically several hours on a single LN2 fill

Applications:

• Fourier Transform Infrared (FTIR) spectroscopy

• Thermal imaging or radiometry systems

• Laboratory research requiring low-noise IR detection

• Replacement assembly for older analytical instruments
