Abstract
The present invention relates to a sight with an optical sighting instrument which includes a lens device with a concave, semi-transparent mirror which is disposed to reflect the image of a light source into the field of view of an eye which is directed towards the concave side of the mirror and observes a target through the lens device. According to the invention, the lens device (1-3), in which the mirror (1) is included, is optically combined with a second lens device (4) which is movably disposed with respect thereto, both lens systems (1-3 and 4) together forming one optical system which is substantially zero-refractive, that is to say neither magnifying nor reducing, and the second lens device is adjustable in two directions which are substantially at right angles to each other and to the major axis (O-F) of the concave mirror surface.
