Olympus OM 35mm film system close-up and macro equipment
PM-SDM Light Shield Tube
Introduction
The PM-SDM Light Shield Tube was designed for connecting an OM body to a microscope in conjunction with the Auto Bellows and the Objective Lens Mount PM-MTob. It assured excellent images when used with FK photo eyepieces at the bellows length of 111 mm (4.4″), free of shutter vibration

Versions
There seems to have been a different version for use with the PM-PSS Photomicrographic Supporting Stand. When an FK or NFK photo eyepiece is used, the large part of the two-piece Light Shield Tube must first be put on the microscope photo tube. Then the small part of the Light Shield (the rubber collar) is slid on the tube of the photo eyepiece, after which it is inserted slowly in the microscope photo tube.

There was also a Light Excluding Collar PM-SDM-2 with an OM bayonet mount, for connecting the PMT-35 auto bellows to the photo tube of a microscope in conjunction with a PM-ADF eyepiece adapter.
