Abstract
A stereomicroscope has light beams of two separate radiation paths passing through two partial pupils directed into a common lens system by at least two mirrors arranged on the level of the pupils. The partial beams are superimposed with the partial pupils spatially separated at the level of the pupils. A separating device with at least one movable diaphragm or at least one tilted mirror, stationary or adjustable along a common axis, provides undistorted images from both partial beams toward at least one image pick-up device. The movable diaphragm shields the partial beams alternately at the level of one of the pupils or the tilted mirror is arranged at the level of the pupils so that both partial beams can be retransmitted separately.
