Blackbody Calibration Source ME30

24. May 2011

According to the latest development in technology
a Blackbody Calibration Source has to be used to
calibrate infrared radiation thermometers and thermal
imaging systems with temperature ranges within –20 °C to 350 °C.
   
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.
