ABSTRACT:
A reference source of heat radiation for the contactless measuring of temperature by photothermometry. The source includes a heat-radiating target connected with an electrically-heated ceramic heating element arranged in a protective guard. The guard is provided with a hood which protects the target from the incidence of light from the observed object, the temperature of which is being measured.
