LOMO 5-axis Universal Fedorov Stage

3D ModelNoAI

Serial No.: 9727

Size: 14 x 10 x 7 cm

Description: This is a Fedorov 5-axis Universal Stage for polarizing microscope made in Soviet Union. All the accessories including the lenses, holders, and glass hemispheres are omitted in the 3D reconstruction.

E.S. Fedorov developed a 4-axis universal stage in 1892 in response to a need to characterize feldspar-group minerals.

The optical behavior in crystals (except those in isometric system) varies with the direction of light travel within the crystal, and measurement of optical properties has to be carried out in specific orientations. The universal stage is certainly the most important of such devices, and for more than half a century it was considered essential for petrographic work. Fedorov Universal Stages have been developed with 2, 3, 4 or 5 axes.
