Abstract
A night vision device has a lens (1) arranged along an optical axis (A) and focusing the low-level light emanating from an object to be observed onto an entry window (2) of a low-light-level amplifier (3). An optical module (6-8) projects the object image available at the exit window (4) of the low-light-level amplifier (3) and represented in a predetermined wavelength range onto at least one receptor, such as a human eye (9). The beam path between the exit window (4) of the low-light-level amplifier (3) and the receptor (9) is determined by reflective optical elements (6, 8), one (8) of which is located along an axis (B) leading to the receptor (9) essentially parallel to the axis (A) of the lens (1) and is essentially reflective for the predetermined wavelength range of the low-light-level amplifier (3) but, if required, essentially transparent for other wavelength ranges.
