Viewing apparatus with adjustable alignment marker support

摘要

A viewing apparatus suitable for use as a night sight includes an image intensifier (3) arranged between an objective (1) and an ocular (7). An alignment member (25) has an alignment marker (28) arranged between the image intensifier (3) and the ocular (7) adjustable by rotation of an alignment marker support (23) about two orthogonal axes (X, Y) which intersect each other at a virtual point of rotation (M) which is located on an optical axis (17).
