A stable base for an operating microscope.

We developed a 1/4-inch mild steel plate underbase with reinforced steel angles and three-inch diameter casters for our nonmotorized operating microscope floorstand. When fully weighted with an automatic focus zoom microscope head, a stereoscopic assistant scope, and a television camera, the unit proved stable and safe. It can be moved more easily than the existing floorstand.
