Abstract

A device having night vision capability, in particular a laser distance-measuring device, has at least two optical channels (A-C), of which a first (A) focuses the low-level light emitted by an object by a mirror (2) and of an optical system (3) onto the entry window (4) of a low-light-level amplifier (5). The image of the object, which is available at the exit window (6) of the low-light-level amplifier (5), is displayed in a predetermined wavelength range and is electronically amplified, and is projected by a further mirror (8) to a receptor (13') on the second optical channel. The first optical channel (A) responsible for night observation has at least one of the mirrors (2; 8) in the form of a first splitter mirror (2; 8) which can be switched on or off and reflects the light in the predetermined wavelength range but is essentially completely transparent for the laser wavelength. Furthermore, in addition to the optical system (3) focusing the low-level light emitted by an object onto the entry window (4) of the low-light-level amplifier (5), a further optical system (7) is also provided which focuses the electronically amplified image of the object, available at the exit window (6), in an associated image plane (10).
