Abstract
An optical device designed to be arranged on a detector provided with an infrared sensor for increasing the angle of the field of view of the detector. The device includes a primary mirror and a secondary mirror that face each other. The primary mirror collects the infrared radiation from a wide-angle field of view to return it to the secondary mirror, which in turn reflects it back to the sensor of the infrared detector.
