ABSTRACT:
An afocal spectral converter as adaptor for existing aiming and sighting devices for the conversion for instance of a heat picture into a visible picture. The arrangement includes the combination of an infrared picture receiving unit with a picture reproducing unit in such a way that the entire system has the enlargement 1:1. The connection of the adaptor with the main device is such that the optical axis of the picture receiving unit is parallel to the optical axis of the main device, and the parallel ray bundle of the picture reproducing unit is so imaged into the main device that the latter will not be influenced.
