J14 Series Lead Selenide Detectors
The J14 Series detectors are Lead Selenide (PbSe) photoconductive (PC) detectors designed for operation in the 2-6 µm wavelength region. The wavelength of peak response depends on the operating temperature and varies from 4 to 4.7
µm. These detectors provide an economical means of obtaining high performance in a rugged and compact package. They are offered in flat plate cells, TO-style packages both with and without thermoelectric coolers which provide low temperature operation for increased sensitivity, longer wavelength operation and temperature stability. Parts listed here are Judson standard product offering. Custom detectors and specifications are offered with built-in electronics and discreet filters. Multiwavelength detectors and arrays are routinely provided in prototype through production quantities. Judson room temperature PbSe provides exceptional performance with minimum peak D* two to three times what other manufacturers offer as standard specifications.
J14P Series Room Temperature PbSe Plate Cells: These basic detecting elements consist of a sensitized PbSe film, electrodes and two electrical leads encapsulated on a quartz substrate. They come standard in active areas from 1 to 3 mm square. Judson room temperature PbSe provides exceptional performance with minimum peak D* two to three times what other manufacturers offer as standard specifications.
J14TO Series Room Temperature TO Packaged PbSe Detectors: These detectors are fabricated utilizing a hermetically sealed and inert gas backfilled TO-5 style semiconductor package. This package protects the active element and
provides the versatility of directly soldering or plugging into a PC board during manufacturing.
J14TE1 Series 1-Stage Thermoelectrically Cooled PbSe Detectors: The J14TE1 Series detectors are high quality temperature stabilized PbSe detectors mounted on a one-stage thermoelectric cooler with a thermistor for control and stabilization of the detector element.
J14TE2 Series 2-Stage Thermoelectrically Cooled PbSe Detectors: The J14TE2 Series detectors are high quality temperature stabilized PbSe detectors mounted on a two-stage thermoelectric cooler with a thermistor for control and
stabilization of the detector element.
J14TE3 Series 3-Stage Thermoelectrically Cooled PbSe Detectors: The J14TE3 Series detectors are high quality temperature stabilized PbSe detectors mounted on a three-stage thermoelectric cooler with a thermistor for control and stabilization of the detector element. At the standard operating temperature of -60°C, this detector offers exceptional sensitivity in a compact and easy to integrate package. Peak detectivity is greater than 4.7 µm.
