ABSTRACT:
A system and method for referencing an objective lens to a desired plane of focus. In one embodiment, a dichroic element is utilized to reflect energy of one or more wavelengths that has passed through an objective lens to a detector for determining a position of the objective lens to a desired plane of focus. The objective lens may be manually and/or automatically focused to the desired plane of focus.
