ABSTRACT:
A catoptric type radiation thermometer having a catoptric type optical system is provided with a light receiving member for receiving an infrared ray emitted from an object to be measured. The infrared ray is periodically prevented and allowed to pass by a shutter blade fixed to an optical chopper supported by a bimorph cell vibrated by an AC signal. The optical chopper is arranged in such a manner that the longitudinal direction thereof is perpendicular to an optical axis of the optical system and the transverse direction is parallel to the axis and that one end of the chopper is supported at the outside of the passageway of the infrared ray.
