Abstract

A binocular microscope having a range of variable magnifications extending from 4X to 20X that is suited to microsurgery and other applications. The microscope has a folded optical axis that places the eyepiece directly in line with the work area. The projected line of sight of a viewer looking through the eyepiece is incident on the work area. This enables the viewer to have normal eye-hand coordination. The folded optical axis also provides a compact configuration that provides a large, clear and unobstructed access to the work area.
