Device for coaxially shifting optical path with thread cross image, has microscope attachments provided with eyepieces, microscope structure lens and optical path that runs according to microscope attachments coaxial to optical axis of lens

摘要

The device has microscope attachments (1) provided with eyepieces (2, 3), a microscope structure lens (4) and a parallel optical path, which is provided with a thread cross image in a microscope structure with the parallel optical path. The parallel optical path runs according to the microscope attachments coaxial to an optical axis (7) of the lens, and an optical path displacement is realized over a prism or two mirrors. The optical axis of the lens and a symmetry axis of each microscope attachment remain concentric to each other.
