NERC 21561 IR detector

Product Description

New England Research Center (NERC) Model 21561 Infrared Detector

This is a high-performance infrared detector from New England Research Center (NERC), a specialist in advanced IR sensor technology. Likely designed for military, aerospace, or scientific applications, it is optimized for mid-wave (MWIR) or long-wave (LWIR) infrared detection with high sensitivity and fast response.

Key Specifications (Interpreted from Model):

• Model: 21561

• Detector Type: Likely InSb (Indium Antimonide) or HgCdTe (Mercury Cadmium Telluride)

• Spectral Range: 3–5 µm (MWIR) or 8–12 µm (LWIR) depending on configuration

• Cooling: May require thermoelectric (TE) or cryogenic cooling (Dewar assembly)

• Package: Hermetic metal or ceramic housing with window (likely germanium or zinc selenide)

• Output: Low-noise analog signal

Potential Applications:

• Infrared spectroscopy or thermal imaging systems

• Missile seeker or FLIR system component replacement

• Research setups for MWIR/LWIR detection

• High-end hobbyist or educational IR sensing projects
