What is a Blackbody Calibrator?
A blackbody calibrator (or blackbody source) is a device that emits thermal radiation with high emissivity, typically near 1.0. This makes it behave closely to an ideal blackbody, emitting radiation according to Planck’s law.
Blackbody calibrators are essential tools for ensuring the accuracy of:
- Infrared thermometers
- Thermal imagers
- Non-contact temperature measurement devices
By aiming a device under test at the precisely controlled blackbody target, users can verify and adjust readings to ensure accuracy and compliance with calibration standards.
