Infrared detectors for aerospace applications encompass photodetector arrays and focal plane arrays (FPAs) sensitive to short-wave, mid-wave, and long-wave IR bands, utilising semiconductor materials such as indium antimonide (InSb), mercury cadmium telluride (HgCdTe/MCT), and quantum well infrared photodetectors (QWIPs), typically requiring thermoelectric or cryogenic cooling via Stirling-cycle or Joule-Thomson systems for optimal sensitivity in FLIR, missile approach warning (MAWS), and EO/IR targeting applications.
How many distinct aircraft programs each supplier in this area is linked to in our database — a proxy for how widely established a company is across the industry. Bars are relative to the top-ranked supplier.
Whether supply here is concentrated in a few big players or spread across many. Top-5 share is the portion of all program links held by the five largest suppliers. HHI (Herfindahl–Hirschman Index) runs 0–10,000: under ~1,500 is competitive, over ~2,500 is concentrated.
