VIGO Photonics - Model PC-9-AF1×1-TO39-NW-90 - HgCdTe (MCT) Photoconductive Detectors
FromVIGO Photonics
PC-9-AF1×1-TO39-NW-90 is uncooled IR photoconductive detector based on sophisticated HgCdTe heterostructure for the best performance and stability. In order to make this detector immune to unwanted optical fringing effects, VIGO developed anti-fringing technology (internal modification of substrate’s surface) and successfully applied it. This results in the fringing 10 – 40 times smaller compared to the standard IR detector.
