Blackbody Radiation Sources & Infrared Calibration Sources
ISDC manufactures precision blackbody radiation sources for MWIR and LWIR radiometric calibration, infrared detector characterization, focal plane array (FPA) testing, and IR system integration. All models emit calibrated Planck (thermal) radiation and are available with NIST-traceable calibration. Typical applications include NETD measurement, D* (specific detectivity) characterization, non-uniformity correction (NUC) of focal plane arrays, FTIR spectroscopy reference sourcing, and IR target signature simulation.

Cavity Blackbody Sources
High-emissivity (>0.99) recessed-cone cavity emitters in apertures from 0.25″ to 2.25″. Temperature ranges of 50°C to 1200°C covering Near-IR, MWIR, and LWIR bands. Ideal for infrared detector calibration, NETD measurement, D* testing, and FTIR spectroscopy.
- Models: IR-508, IR-518, IR-519, IR-563, IR-564, IR-565, IR-574, IR-704
- Emissivity >0.99 | NIST-traceable calibration
- 0.25″ – 2.25″ apertures
Extended Area Blackbody Sources
Flat-plate emitters with 12″ × 12″ active area and high-emissivity coating (0.96), plus thermoelectric (TE) cooled compact models for sub-ambient operation. Ideal for FPA non-uniformity correction (NUC), thermal imager calibration, and large-target IR scene simulation.
- Models: IR-140, IR-150, IR-160, IR-2100, IR-2103, IR-2106
- Emissivity 0.96 ± 0.02 | NIST-traceable calibration
- −30°C to 500°C range | 12″×12″ to 2″×2″ active areas
