PVMQ

2.0 – 12.0 µm HgCdTe ambient temperature photovoltaic multiple junction

quadrant detector

PVMQ is 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.
