Abstract: An apparatus is presented for attaching a lens to a microscope with an optical attachment. The apparatus includes the lens with a translational degree of freedom such that the lens is configured to translate along a first direction relative to the microscope and the optical attachment. A system is also presented that includes the apparatus and the optical attachment. The optical attachment includes a lens holder and/or the viewing attachment configured to move the lens and the lens holder relative to the microscope. A method is also presented for using an optical attachment to position a hands-free lens relative to a microscope.

Abstract: An apparatus is provided including a sterile cover. The sterile cover includes a first portion (202) that defines a first cavity such that the first portion is configured to secure a non-sterile inverter (106) of a wide angle viewing attachment for a microscope within the first cavity. The sterile cover also includes a second portion integral with the first portion. The second portion defines a second cavity continuous with the first cavity. The second portion is configured to secure an imaging lens (201) of the microscope within the second cavity. A method is provided for using the microscope including the apparatus. A method is provided for forming the apparatus.
