Product offeringCore offering
InfraRed Associates designs, develops, manufactures, and sells Mercury Cadmium Telluride (HgCdTe/MCT) and Indium Antimonide (InSb) infrared detectors covering the 1 to 25 micron wavelength range, available with LN2, Thermoelectric, and Stirling cycle cooling options. The company also manufactures multi-element photoconductive arrays up to 128 elements, two-color detectors, pre-amplifiers (MCT-1000, INSB-1000), and supporting accessories such as temperature controllers, power supplies, heat sinks, and dewar valve operators. Products are sold directly to OEM customers for defense, analytical, medical, environmental, and industrial applications.
Product overview
InfraRed Associates is a specialized manufacturer of high-quality HgCdTe (Mercury Cadmium Telluride) and InSb (Indium Antimonide) infrared detectors with a legacy dating back to 1976. The company offers a comprehensive product portfolio spanning single-element detectors (HgCdTe MCT Detectors, InSb Detectors), multi-element arrays (up to 128 elements), and various cooling options (Liquid Nitrogen, Stirling closed cycle, and Thermoelectric coolers). Supporting products include pre-amplifiers (MCT-1000, INSB-1000), temperature controllers, power supplies, heat sinks, and standard packaging solutions. The company was acquired by VIGO Photonics in March 2026.
