The Mikron® M315X-HT blackbody calibration sources meet the exacting parameters of infrared focal plane array detectors, thermal imagers, and FLIR systems testing in projection scenes and field applications where higher temperatures are required.

The M315X-HT blackbody sources are resistively heated by precision heating elements to provide uniform temperature distributions. The two-piece system is comprised of the controller module and a separate enclosure for the emitter source.

Emitter source temperature control is carried out by a precision digital PID controller, mounted in a 7 in (180 mm) high 19 in rack mount enclosure. 


  • Select from four aperture sizes from 4 x 4 in to 12 x 12 in
  • Calibrate and verify the output signals of pyrometers, thermal imagers, etc.
  • Achieve high accuracy and repeatability
  • Control emitter source temperature with a precision digital PID controller


  • High emissivity with unchallenged stability and uniformity
  • Uniform temperature distribution with precision heating elements
  • Furnished with a certificate of calibration traceable to NIST
  • RS232 (standard) or RS485 serial communication
  • Stable RTD ensures long-term temperature stability of the system
