To calibrate infrared pyrometers and thermal imaging systems accurately, it is necessary to have a source of IR radiance that is controlled and predictable. PSC-BBS series of blackbody calibration sources provide a target of known emissivity, temperature and aperture size. These blackbodies can also provide calibration traceability to certified laboratories and national standards.
