Lead Selenide and Lead Sulfide IR Detectors

Cal Sensors (Santa Rosa, CA) has announced the launch of IDA (Integrated Detector Assembly) lead selenide and lead sulfide high-sensitivity infrared detectors with integrated electronics enclosed within a compact, hermetically sealed TO-8 package. Housing the electronic drivers within the detector package enhances noise performance since the detector is as close as possible to the first stage of amplification. This enables greater low signal detection capability for sensing trace elements by improving dynamic range. Covering the 1.0 to 5.5μm infrared region, IDA detectors provide industry leading sensitivity of 1.5E10 Jones. IDA lead selenide (2.8 × 10¹⁰ cm Hz^1⁄2 w^-1 peak D*) and lead sulfide (1.5 × 10¹¹ cm Hz^1⁄2 w^-1 peak D*) detectors are available in both 1mm and 2mm square sizes.
