PVM-8

HgCdTe (MCT) Photovoltaic Detector

2.0 – 9.0 µm, ambient temperature, multiple junction

PVM-8 is an uncooled IR photovoltaic multiple junction detector based on sophisticated HgCdTe heterostructure for the best performance and stability. The detector is optimized for the maximum performance at λ_opt = 8.0 μm. It especially useful as large active area detector operating within 2.0 to 9.0 µm spectral range.
