Claims

[Claims for Utility Model Registration] (1) An infrared radiation thermometer body that measures the temperature of a measurement object without contact by concentrating infrared rays emitted from the measurement object onto an infrared sensor via an infrared focusing system. and at least two visible light beam sights that focus and intersect visible light beams toward the object point whose temperature is to be measured from different directions, and the visible beam sights include a visible light source and a deflector that polarizes and focuses the light beams emitted from the visible light source An infrared radiation thermometer characterized by having. (2) The infrared radiation thermometer according to claim 1, wherein the deflector is a convex lens arranged at an angle with respect to the central axis of the sighting barrel. (3) The infrared radiation thermometer according to claim 1, wherein the deflector is an equally divided convex lens arranged at an angle with respect to the center of the sighting barrel.
