The part indicated by the arrow is φ45. Because all of our microscope stand lens holder parts are φ50mm, they cannot be fixed as they are.
Our company offers lenses in various sizes. We manufacture adapter rings to convert all lenses to φ50mm.

 

The adapter rings produced by our company are available in the following four sizes:

– φ46mm → φ50mm
– φ40mm → φ50mm
– φ32mm → φ50mm
– φ28mm → φ50mm

For sizes other than these, production will be carried out upon receiving the order.
