This adapter allows using microscope objectives with M40x36tpi mount thread (like Mitutoyo BD) in front of lenses with M52x0.75 filter thread (for macrophotography purposes).

Front side of the adapter has also female M52x0.75 thread to allow you using your usual accessories (like circular light) in this setup.

M40x36tpi thread is made with large enough tolerances to accept M40x0.75 thread as well.

Made of anodized aluminium.
