Teledyne FLIR Space

Thousand Oaks, United States commercial

Teledyne FLIR Space is the space-dedicated product division of Teledyne FLIR (part of Teledyne Technologies, NYSE: TDY), headquartered in Thousand Oaks, California, providing infrared imaging systems, focal plane arrays (FPAs), and complete camera systems for Earth observation satellites, planetary science missions, defense surveillance payloads, and space situational awareness instruments. FLIR's space heritage traces through multiple legacy companies assembled by Teledyne's acquisition strategy — including Santa Barbara Research Center (SBRC, formerly part of Raytheon/Hughes) and other infrared detector specialists. Teledyne FLIR Space's core technology is semiconductor-based infrared detector arrays — the focal plane arrays at the heart of thermal and near-infrared cameras. For space applications, FLIR produces indium antimonide (InSb), mercury cadmium telluride (HgCdTe, also called MCT), and microbolometer detector arrays that operate across wavelength ranges from near-infrared (0.8–2.5 µm SWIR) through mid-wave infrared (MWIR, 3–5 µm) and long-wave infrared (LWIR, 8–14 µm). These wavelength bands enable different application types: SWIR for daytime vegetation analysis and cloud-penetrating imaging, MWIR for missile plume detection and fire sensing, LWIR for land surface temperature and atmospheric emission measurements. Space mission heritage includes FPAs for NASA's WISE (Wide-field Infrared Survey Explorer) telescope that catalogued over 700 million objects, instruments on the Mars Reconnaissance Orbiter, thermal imaging systems for NOAA weather satellites, and detectors for various classified defense reconnaissance systems. The JWST (James Webb Space Telescope) uses near-infrared detector arrays where Teledyne FLIR's legacy sensor technology is present in the NIRCam, NIRSpec, and FGS instruments — among the most technically demanding infrared detectors ever built, requiring operation at 37 K and achieving noise levels measured in electrons per pixel per hour. Teledyne FLIR Space competes primarily with Raytheon (now RTX) Vision Systems, DRS Technologies (Leonardo DRS), and Sofradir (now Lynred, France) for the infrared focal plane array market.
