The nomenclature can be explained using the following example: PB50S3030T27L. This is a designation for multistage cooled PbSe detectors with a standard cooler, sapphire window, square chip 3.0×3.0mm², dual stage cooling in a TO-37 housing with a long cap.
TE-cooled PbS & PbSe detectors announced
The LASER COMPONENTS Detector Group has reached its next milestone with its first delivery of TE-cooled detectors. Single-stage and multistage cooled PbS versions are available under the designations PB27 for standard coolers and PB30 for special coolers. The designations of the analogous PbSe series are PB50 and PB55.
