Vintage USSR. METALLOGRAPHIC MICROSCOPE MMU-3. LOMO.

Description

The MMU-3 metallographic microscope is designed for visual observation of opaque objects in reflected light when working in bright and dark fields and in polarized light. The MMU-3 metallographic microscope is used in factory laboratories and directly in workshops. On the MMU-3 metallographic microscope, it is possible to photograph the image of objects using microphotographic attachments of the MFN type.
