Abstract
A radiation thermometer comprises an optical objective through which radiation to be detected passes. A beam splitter has a central region through which a central portion of the radiation which has passed through the objective passes undeflected and an outer region which reflects radiation surrounding the central portion. An eye piece receives radiation passing through the beam splitter; and a radiation detector receives radiation reflected by the beam splitter.
