Surgical microscope system.

摘要

A surgical microscope comprises an illuminating light source for observation and/or photographing, an observation optical system, an index projecting optical system and a cornea configuration measuring optical system. The index projecting optical system includes an index which is removably inserted in the illuminating light beam emitted from the illuminating light source and transmitted through an objective of the observation optical system, thereby dispensing with any particular light source for measuring a cornea configuration, and a cornea configuration measuring mode and a photographing mode being automatically changeable by automatically detecting the presence or absence of the index within the optical path of the microscope.
