PV-5-AF1×1-TO39-NW-90

HgCdTe (MCT) Photovoltaic Detector

Ambient temperature, with anti-fringing technology

PV-5-AF1×1-TO39-NW-90 is uncooled IR photovoltaic 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.
