3 Watt Cooled PbSe Detectors can extend the wavelength range of detectable gases, increase signals, and improve the detection rate and signal-to-noise ratio of the lead Selenide detector.
Compared with 2 Watt Cooled PbSe Detectors, the 3 Watt Cooled PbSe Detectors can have the higher signal, thus, it is suitable for the lower LDL gas detection.
3 Watt Cooled PbSe Detectors is also an ideal choice for applications in temperature changing environments, as by adjusting the TEC current, the temperature of the infrared detector element can be maintained stable, reducing the detection signal drift caused by temperature changes.

Brand Introduction:
Infrared Materials Incorporated is a manufacturer of high performance Lead Sulfide (PbS) and Lead Selenide (PbSe) IR detectors and array components, sensitive in the IR spectral range of 1– 5.5 microns. PbS and PbSe detectors are commonly used as the critical sensing element in commercial process control systems, industrial gas monitors, spectroscopy, imaging, and medical CO2 gas analyzers, fire & spark detection systems, combustion control systems, moisture analyzers, and flash detection systems.
Infrared Materials has extensive experience in building drop-in replacement assemblies in single and multi-channel configurations to match the form, fit, and functional requirements of one-off prototype projects and production level programs. The detectors are produced in Santa Rosa, California and distributed through representatives worldwide.
