An objective lens cover assembly for employment in a sterile or nonsterile disposable operating microscope drape. The assembly includes a housing adapted to frictionally engage the objective lens frame of the microscope, and to removably receive a lens cover in positive locking and sealing engagement therewith. The housing includes a circumferential flange for seating the lens cover, and a resilient peripheral portion extending downwardly from said flange for receiving the lens cover. The resilient peripheral portion includes resilient lens cover retaining means including a plurality of inwardly deflectable projections, each having a base face spaced from the circumferential flange to define lens cover retaining slots. When the lens cover is received in the housing, the lens cover deflects the lens cover retaining means outwardly to seat the lens cover in the retaining slots. The lens cover is disengaged from the housing by flexing the lens retaining means outwardly.

Objective lens cover assembly for an operating microscope

A light distributor is described for use in distributing light from a source in a generally uniform manner across an edge, to for example, illuminate an array of light sensitive elements. The light distributor can be made of a transparent plastic material and is formed with a light guide and a lamp supporting segment. The light guide has a pair of planar faces bounded by sides of a curvature, which bears a particular relationship with a light source region in the lamp supporting segment so as to distribute light therefrom across the edge. A cost effective efficient light distributor is described, particularly for use in activating photocells arranged in an array in a shaft encoder.
