2-12 µm; Active Area 1 mm²; Responsivity ≥0.002 A/W; Detectivity ≥9.0×10⁶-≥2.0×10⁷ cm·Hz^1/2/W; Resistance 30-≤240 Ω; Package TO8

Vigo System’s PVMQ and PCQ series comprise of HgCdTe (MCT) infrared (IR) detectors whose active surface consists of more than two elements. The offer includes quadrant geometry detectors based on photodiodes and photoconductors, ideally suited for defense and security applications as well as XY or differential measurements.

PVMQ and PCQ are 2 µm to 11 μm uncooled, ambient temperature IR detectors, based on sophisticated HgCdTe heterostructures for the best performance and stability. These quadrant detectors consist of four separate active elements arranged in a quadrant geometry and optimized for maximum performance at 10.6 μm. The main application of PVMQ/PCQ detectors is laser beam profiling and positioning.

PVMQ is a photovoltaic multiple junction quadrant IR detector, while PCQ is a photoconductive quadrant IR detector. The PCQ detector should operate in optimum bias voltage and current readout mode, and its performance at low frequencies is reduced due to 1/f noise.
