ABSTRACT:
An optical device for a micro-image viewer or a micro-image viewer-printer machine receives a projected image of an illuminated micro-image, adjusts the spatial disposition of the projected image in an image plane and transmits the adjusted projected image to a viewing screen for viewing or to an exposure station for reproduction purposes. The optical device, in a preferred embodiment, includes a pechan prism positioned in a micro-image viewer-printer machine for receiving a projected image from a projection lens assembly. The pechan prism is rotatable about the illumination path or optical axis of the viewer-printer machine to enable the spatial disposition of the projected image to be rotated at least from 0 degrees to 180 degrees in an image plane. The pechan prism is mounted in the optical axis of the viewer-printer machine by a novel mounting assembly that enables both the controllable rotational movement of the pechan prism about the optical axis and the controllable longitudinal movement of the pechan prism along the optical axis. Additionally, the novel mounting assembly enables the pivotal movement of the pechan prism into and out of the optical axis to provide access to the projection lens assembly for the adjustment, repair, removal and replacement of the projection lens assembly.
