Abstract: A universal inner diameter mounting ring contains an annular groove within its inner circumference, the ring being integral with a microscope drape. A microscope adapter housing having a universal outer diameter with a protruding annular ring around its circumference engages the groove on the mounting ring. The adapter engages the inner mounting threads of a microscope body at a first end and the threads of an objective lens housing at a second end.
