Abstract: An infrared thermometer measures a temperature of an energy zone. The infrared thermometer comprises a beam splitter for splitting an incident light beam from an energy zone into an infrared light beam and a visible light beam; an infrared detector for detecting the infrared light beam and generating a signal indicative of a temperature of the energy zone according to the detected infrared light beam; and a sighting device having an optical module for generating a reflective reticle image and transmitting the visible light beam to generate a target image at a sight window, wherein the sighting device is configured to superimpose the reflective reticle image over the target image at the sight window to align the infrared detector with the energy zone. The infrared thermometer and an associated measurement method facilitate the alignment of the energy zone by the users, thereby improving the accuracy of the measurement.
