Abstract:
Device having night vision capability, comprising at least two optical channels (A, B, C), of which a first channel (A) focuses the low-level light emitted by an object, by means of a first mirror (2) and an optical system (3), onto an entry window (4) of a low-light-level amplifier (5), from which the image of the object which is available at the exit window (6) of the low-light-level amplifier (5), displayed in a predetermined wavelength range and electronically amplified is projected by means of a second mirror (8) to a receptor (13â€²) on the second optical channel, characterized in that the first optical channel (A) responsible for night observation has at least the following optical components:a) one of the mirrors (2; 8) is designed as a first splitter mirror (2; 8) which can be switched on and off and reflects the light in the predetermined wavelength range but is essentially completely transparent for another wavelength; b) a further optical system (7) which focuses the electronically amplified image of the object which is available at the exit window (6) in an associated image plane (10).
