About Us

Teledyne Judson

Teledyne Judson Technologies (TJT) is a global leader for IR sensors from the Visible to VLWIR spectrum. Two dimensional focal plane arrays (InGaAs, InSb, and MCT) and Integrated Dewar Cooler Assemblies (IDCAs) complement our single element infrared detector portfolio. ​Markets utilizing our focal plane arrays include surveillance, law enforcement and security, laser beam diagnostics and range finding, chemical and biological detection, and spectroscopy. Supplementary electronics, optics, Peltier cooling and cryo-cooled modules are also offered.

Our high performance single element infrared detectors utilize a wide variety of materials such as Indium Gallium Arsenide (InGaAs), Mercury Cadmium Telluride (HgCdTe), Indium Antimonide (InSb), Indium Arsenide (InAs), Lead Sulfide (PbS), Lead Selenide (PbSe), and Germanium (Ge).  Room temperature, thermoelectric coolers, as well as cryogenic dewars are available.
