ABSTRACT:
In a microscope the eyepiece and the objective lenses are separately mounted, the objective being mounted in a cantilever member which is rigidly attached to a rigid portion of a support pillar. The eyepiece is also cantilevered out from the support pillar, the eyepiece cantilever being spaced away from the objective-mounting cantilever and entirely free of contact therewith, except only the remote contact through the pillar. To maintain the most rigid possible relationship between objective and stage, the stage is focusably mounted on a rigid portion of the same support pillar. With the stage-to-objective distance, or object conjugate, held firm and relatively free of vibrations the distance to the eyepiece focal plane, or image conjugate, is much less critical; therefore the eyepiece support member, while also relatively rigid, is less so than the pillar and it tends to absorb vibrations emanating from the eyepiece area and to isolate both the stage and objective mounting members from the eyepiece mounting members, thereby reducing the degree to which such vibrations can affect the critical object conjugate. The effect of vibration may be minimized even more by letting the objective furnish an infinite focus, the image being viewed by a telescopic eyepiece.
