A red temperature calibration begins with a measurement of what is acting as a heat source, which must be a target plate or a capacity that functions as a standard or reference. The calibration geometry, which includes the size of the measurement surface and the distance of the thermometer to be calibrated, depends on the result of the measurement. Also critical are the stability of the tem e ra t, the u nity and the properties emission V i dad.

Emissivity is the energy r a d e a n t e coming from an opaque surface and is a combi nation of the emitted radiation caused by the tem perature of the surface and the reflected radiance arising from any radiation in the atmosphere.

The amount of light emitted at a certain temperature is determined by the emissivity of the surface. The emissivity is the relationship between radiated energy. emitted by a surface and emitted by a black body at the same temperature. The operation is greatly affected by the operation of the area and the completion of the same.

It is only for an ideal body that the emissivity is independent of its temperature and wavelength.
