Abstract
An optical system of colposcope comprises a pair of independent observation optical sub-systems each having a family of objective lenses including a magnification varying optical sub-system, the magnification varying sub-system in one observation sub-system being ganged with the magnification varying sub-system in the other observation sub-system. The optical system also comprises a photographing optical sub-system having a family of objective lenses including a magnification varying optical sub-system which is ganged with the magnification varying sub-systems of the observation sub-systems, and an illumination optical sub-system for illuminating an object being examined. The observation, the photographing and the illumination sub-system are disposed so that their optical axes converge on the object being examined.
