•Depression angle: 30°

•Tube magnification: 1X

•Special beam splitter offers brighter images.

•Owing to Siedentopf type adopted, even though the interpupillary distance is changed between 51 - 75 mm, for which prism cover @is vertically tumed and moved, the tube length keeps

constant ali the times.
