Abstract
An optical device that can be sterilized by autoclaving or immersion. The optical device includes adjoined elements that essentially eliminate any air internal spaces along the optical path. A carrier for the optical elements and other elements of the optical device comprise metals and metal alloys that withstand the sterilizing environment. Vacuum port elements are provided to enable any liquids to be evacuated from the interstices of the optical device.
