Claims

[Scope of claim for utility model registration] Directing the emitted light from the object to be measured to the light receiving sensor through an optical fiber,
In the radiation thermometer that measures the temperature of the object to be measured based on the light received by the light receiving sensor, the radiation thermometer includes: a calibration light source that irradiates calibration light; a calibration light receiving sensor;
During calibration, the calibration light from the calibration light source is split into two by a beam splitter, one of which is guided to one end face of the optical fiber and eyeglass, and the other is guided to the calibration light receiving sensor.The light that is guided to the optical fiber is Calibration light control means that reflects the light at the other end surface and guides it to the light receiving sensor after reciprocating within the optical fiber; and a light loss in the optical fiber based on the light received by the light receiving sensor and the calibration light receiving sensor A radiation thermometer characterized by comprising a compensation circuit that compensates the measured temperature according to the optical loss.
