Optical, image producing device

摘要

An optical, image producing device of the Camera Lucidas type is provided wherein the panel on which the optical image is superimposed may be supported at different angles of inclination on a base, to which a mirror assembly carrying column is rigidly attached, so that the inclination of the panel can be adjusted allowing the device to be used tilted to observe an object at different elevations. The column has a viewing aperture which is wide enough for an image to be viewed simultaneously by both eyes to give a panoramic view.
