    Patent number: 5074650
    Abstract: A stereomicroscope includes an objective lens used in common and a pair of observing optical systems on the left and right sides, arranged behind the objective lens so that optical axes of the observing optical systems are symmetrically arranged at a predetermined angle with respect to an optical axis of the objective lens. In the stereomicroscope, the objective lens may be arranged so that a focal length of the objective lens has a positive value and an object is located closer to the objective lens than an object focal point of the object lens, and thereby an image which is high in resolution and favorable in flatness is brought about.
