J13 Series Lead Sulfide Detectors

The J13 Series detectors are Lead Sulfide (PbS) photoconductive (PC) detectors designed for operation in the 1-3.5µm wavelength region. The wavelength of peak response depends on the formulation and operating temperature. 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 and thermoelectric coolers 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 offered with built-in electronics, discreet filter, multiwavelength detectors and arrays are routinely provided in prototype
through production quantities.

J13P Series Room Temperature PbS Plate Cells: These basic detecting elements consist of a sensitized PbS film, electrodes and two electrical leads encapsulated on a quartz substrate. They come standard in a variety of active areas from 1 to 10 mm square.

J13TO Series Room Temperature TO Packaged PbS Detectors: These detectors are fabricated utilizing a hermetically sealed and inert gas backfilled TO-5, TO-8 or TO-3 style semiconductor package. This package protects the active element and provides the versatility of directly soldering or plugging into a PC board during manufacturing.

J13TE1 Series 1-Stage Thermoelectrically Cooled PbS Detectors: The J13TE1 Series detectors are high quality temperature stabilized PbS detectors mounted on a one-stage thermoelectric cooler with a thermistor for control and stabilization of the detector element. At the standard operating temperature of -20°C, the
wavelength peak is 2.5µm.

J13TE2 Series 2-Stage Thermoelectrically Cooled PbS Detectors: The J13TE2 Series detectors are high quality PbS photodiodes mounted on two-stage thermoelectric coolers with thermistors for control and stabilization of the detector element. At the standard operating temperature of -30°C, the wavelength peak is 2.6µm.

J13TE3 Series 3-Stage Thermoelectrically Cooled PbS Detectors: The J13TE3 Series detectors are high quality temperature stabilized PbS 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, the
wavelength peak is 2.7µm. This detector offers exceptional sensitivity in a compact and easy to integrate package.
