徴とする赤外線撮像装置。 In an infrared imaging device comprising an infrared detector and an infrared imaging optical system that forms an infrared image on the infrared detector, the infrared imaging optical system is configured to detect a target at a distance different from an assumed distance when designing the infrared imaging optical system. A distance correction filter is provided in front of the infrared imaging light source system for correcting the transmitted light amount ratio of each wavelength in the atmosphere of the infrared rays emitted by the target to be the same as that at the assumed distance when imaging. An infrared imaging device characterized by:
