HgCdTe (MCT) Photovoltaic Detector

2.0 – 12.0 µm, ambient temperature, multiple junction quadrant

PVMQ-10.6 is an uncooled IR phtovoltaic multiple junction quadrant detector based on sophisticated HgCdTe heterostructures for the best performance and stability. Quadrant detector consists of four separate active elements arranged in a quadrant geometry. The device is optimized for the maximum performance at 10.6 µm. The main application of PVMQ detector is laser beam profiling and positioning.
