Abstract
A microscope in which the lens assembly and viewing stage can be positioned at any of several predetermined angular orientations for ease of viewing, the lens assembly includes a zoom magnification capability, and two slides can be pivotably mounted on the viewing stage for alternative positioning in the lens viewing zone without removal of the viewer's eye from the viewing lens, permitting rapid comparison of specimens. A base member has a curved channel, and a frame member has a curved portion with curvature matching that of the channel, permitting the frame member to be positioned on the base member with an adjustable angular orientation. A locking pin passes through an opening in the frame member and rests in a groove in the base member to retain the frame member at a predetermined angular orientation. An eyepiece has a scalloped lower surface to provide cam portions, and an eyepiece engaging member has ribs which cooperate with the cam portions to alter spacing between the viewing lens and the objective lens as the eyepiece is rotated on the eyepiece engaging member, thereby providing zoom magnification. The viewing stage has a number of holes circumscribing the viewing zone. Each of a pair of swing slides has a peg, positioned in a hole of the viewing state, and a viewing area. The two swing slides can be pivoted to alternatively position the viewing area of each within the viewing zone.
