An ideal blackbody sends out radiation – in a defined wavelength region – which only depends on its temperature. Its emissivity is 1 (Planck’s law of radiation). A surface which comes very close to this perfect radiator is achieved by the aperture of a cavity whose inner surface is blackened and at a uniform temperature.

When the opening is small with regard to the dimensions of the cavity, blackbody behavior is approximated. The emissivity is towards 1. This condition is achieved by a cylinder (tube with a bottom)
when the ratio length to diameter is high. Therefore the opening of the cylinder is excellently suited as a calibration source for infrared radiation thermometers and thermal imaging systems.

The universal blackbody ME30 meets all requirements for adjusting and calibration of radiation thermometers according to VDI/VDE-guideline 3511, Temperature measurement in industry, Part 4 Radiation thermometry and Part 4.4 Calibration of radiation thermometers
