Description

The PCQL series detectors are quadrant, high speed, ambient temperature photoconductive mode IR photodetectors. These devices can be optimized for the maximum performance at 10.6 µm. High performance and stability were achieved by using a newly developed variable gap semiconductors (HgCdZn)Te, optimized composition/doping profiles and improved surface processing. They are housed in rugged packages of reduced size and weight. Performance data are provided with each detector.

The detectors are well suited for pulsed or modulated CO₂ laser application over an extremely wide frequency band due to a very short response time and to the perfect match to fast electronics. Custom devices such as single elements of varius sizes, connectors, windows and optical filters are available on request. Optically immersed devices with performance improved by a factor of 7 are available upon request.
