Abstract
A device for measuring the temperature of a measured spot of a measured object without contacting the measured object is provided. The device includes a detector on which electromagnetic radiation emanating from the measured spot is projected by an optical imaging system. A sighting device for marking the position and/or the size of the measured spot includes at least two light sources. Each of the two light sources provides a respective sighting ray.
