Infrared imaging device

Infrared imaging device comprising an infrared camera having an optical axis (A), said camera being intended to detect an infrared radiation in a spectral range through an element transparent to said infrared radiation, the transparent element being inclined by an angle of inclination (α) greater than 0° and smaller than 90° or smaller than 0° and greater than −90° with respect to an image capture direction (C);

• the device further comprising a refractor element transparent to the infrared radiation in the spectral range and capable of being positioned between the transparent element and the infrared camera, said refractor element comprising a virtual exit facet of the refractor element, corresponding to an exit facet of the refractor element in a tunnel diagram of said refractor element, said virtual exit facet being substantially parallel to an entry facet of the refractor element;
• the transparent element having an entry facet and an exit facet, substantially planar and parallel to each other, being surrounded by a mount, and being adapted to being inserted with said mount into the opening of a wall, at least a portion of the wall in which the transparent element is inserted being inclined by the same angle of inclination (α) as the transparent element.
