Monocular optical inspection system with long eye relief and enhanced depth perception

摘要

A monocular inspection system (10) having a substantial eye relief (62), a large exit pupil, and a line of sight viewing of an object under observation (14). The inspection system (10) includes an objective lens assembly (20) which forms an image of the object (14) and which has an axis coincident with an optical path (66). A prism (16) redirects the optical path (66) to coincide with a viewing axis (64) such that the image is formed in a focal plane intersected by the viewing axis (64). A monocle assembly (40) having an axis coincident with the viewing axis (64) forms an exit pupil for the image.
