Abstract
Apparatus for measuring the temperature of an object comprises an optical tube, a first temperature sensor located at a closed end of the optical tube, a lens located at an open end of the optical tube and arranged to focus radiation from the object onto the first temperature sensor, a shutter located at the open end of the optical tube, the shutter having an open position allowing radiation from the object to reach the first temperature sensor and a closed position preventing radiation from the object reaching the first temperature sensor, a second temperature sensor located on the shutter, a third temperature sensor for measuring the substrate temperature of the first temperature sensor, a control device arranged to open and close the shutter, and a processing device connected to the first temperature sensor, the second temperature sensor, the third temperature sensor and the control device. The processing device is arranged to take first measurements from the first, second and third temperature sensors when the shutter is in its closed position, calculate an offset value from these measurements, open the shutter, take a second measurement from the first temperature sensor, and calculate the temperature of the object from the second measurement, the substrate temperature and the offset value.
