<p>The system has a separating blade (2) e.g. thin prismatic blade, to separate spectral paths in downstream of a convergent dioptric optical head portion (1). Convergent dioptric correction relays (3A, 3B) correct geometric and chromatic aberrations on each path, where the relays have transparent materials in spectral band. A visible spectral band sensor (4A) e.g. charge coupled device camera, and an infrared spectral band sensor e.g. two dimensional matrix (4B), provides a signal on each path. An optical, analogical or digital mixer (10) mixes signals from each sensor. The transparent materials of the relays are based on chalco-halide glass consisting compounds and sulphur such as germaniumsulfide-galliumsulfide-cesiumchloride, lanthanumsulphide-galliumsulfide-cesium chloride and lanthanumsulphide-galliumsulfide-rubidium iodide.</p> |
