Blackbody Calibration Sources

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.


The BBS1500-40 is a highly stable calibration source which provides automatic calibration. It is ideally used for the calibration of short wavelength pyrometers and thermal imaging cameras between 250 and 1500°C. The large aperture size allows for easy alignment between the blackbody and the device under test.

BBS 1050 and BBS 1200 Compact Blackbody Sources

The BBS 1050 and BBS 1200 Compact Blackbody Sources offer high accuracy in up to 1" aperture in a compact form factor. Designed for compact mid to high temperature applications, making them ideal for smaller systems.

BBS 1150 and 1700 Mid to High Temperature Calibration Source

Two Blackbodies perfect for mid to high temperature applications. User selectable temperature set points within 200° to 1150°C (BBS1150) or 300° to 1700°C (BBS1700). Simply adjust the set point on the precision digital PID controller to any temperature within the specified temperature ranges and the two BlackBodies should stablize and begin reading.

BBS400 and 500 Low Temperature Blackbody Sources

Ideal for the verification and calibration of non-contact infrared thermometers, infrared detectors, and imaging systems at lower temperatures. Temperature ranges begin with a low of 5°C to a max of 500°C.

BBS 100 Series TE Cooled Blackbody Calibration Sources

The PSC-BBS100-TE and PSC-BBS120-TE are well suited for the calibration and verification of non-contact infrared thermometers, thermal imaging cameras, FPA (focal plane arrays), and spectrometers. Optional USB interface with software enables the control of the blackbodies via a PC. Temperature ranges begin with a low of -15°C to a max of 120°C.

BBS-FP Fixed Point Temperature Calibration Sources

The BBSxx-FP Blackbody series provides a quick and accurate way to check the calibration of non-contact infrared temperature sensors. Eighteen Blackbody calibration source models are available; offering fixed target temperatures from 35ºC to 150ºC, all providing outstanding stability with less than ±0.2ºC deviation.

BBS EX Extended Area Blackbody Calibration Source

The PSC EX series of black body source offer a range of temperatures in a 12" x 12" black body calibration source.

BBS-EX-TE Blackbody Series

Various Blackbodies with a large uniform extended area emitter plate used for thermal imaging camera calibration and focal point array detectors (FPA). Comes in a variety of emitter sizes and temperature ranges.


The BBS500-57 is a lightweight Blackbody ideal for the calibration verification of pyrometers and thermal imaging cameras. Used for temperature ranges between 50 to 500°C. Cost-efficient and easy to transport, this Blackbody can quickly be used in many plants, laboratories, and factories.
