Japanese Patent JP5771218

Kind Code:

Abstract:

A system for providing a two-position zoom-focus capability in a video inspection device comprising, in one embodiment, a focus lens cell and primary aperture attached to a set of fixed rails and connected to a zoom lens cell. In one embodiment, the focus lens cell is moveable into a first position along the rails through activation of a proximally located lens movement mechanism, and moveable into a second position through relaxation of a tensioned focus spring. In one embodiment, movement of the focus lens cell between first and second focus positions causes movement of the zoom lens cell and a secondary aperture between corresponding first and second zoom and aperture positions to provide unmagnified and magnified images of a target object.
