| 摘要 |
The invention proposes a changer device for optical elements ( 2 a- 2 e) in stereomicroscopes with which a pair of optical elements ( 2 ) can be inserted in the two stereo channels ( 3 ) of a stereomicroscope. A particularly compact construction can be achieved by arranging the optical elements ( 2 ) side by side in an arc, more particularly in a circle, while between the elements of a pair of elements ( 2 a , 2 d) associated with the two stereo channels ( 3 ), at least one other optical element ( 2 e ; 2 b , 2 c) is provided, and in that the center ( 4 ) of the arcuate or circular arrangement ( 1 ) is shifted laterally away from the middle ( 5 ) of the stereobase of the stereo channels ( 3 ).
