ABSTRACT:
A binocular optical system has a pair of six lens optical systems. Each system includes one lens (12) defining an optical axis and the remaining lenses (14, 16, 18, 20, 22) centered on the axis. The lens systems (12, 14, 16, 18, 20, 22) collimate the energy passing through them onto an exit pupil (24) positioned a desired eye relief distance (30) away from the last lens (22).
