HgCdTe room temperature photoelectromagnetic infrared detectorPEM-10.6-1x1-PEM-SMA-wZnSeAR-48
PEM-10.6-1x1-PEM-SMA-wZnSeAR-48 is an uncooled photelectromagnetic IR detector based on HgCdTe heterostructure for optimal performance and stability. Its specific wavelength (λspec) is 10.6 µm and its active area (A) is 1 mm × 1 mm. The detector is available in the specialized PEM-SMA package with an incorporated magnetic circuit inside and a 3 deg. zinc selenide anti-reflection coated window (wZnSeAR) to prevent unwanted interference effects and external pollution.
