This Ukrainian made beam splitter is unusual in as
much as it is a camera attachment that then converts into a stereo
viewer, achieved by inserting the stereo lenses into the lens attachment.
The Beam Splitter takes two images through one
lens onto a single 35mm frame (measuring 36mm x 24mm). The lens
attachment requires a camera with a focal length of 58mm and so is
ideally suited to Zenit (Zenith) cameras. The lens must also have either
a 49mm or 52mm filter thread to screw the attachment onto.
The SKF-1 was initially produced in 1985 and was
manufactured for at least six years, maybe longer.
The SKF-1 Logo found moulded in
the viewer section of the SKF-1 Viewer.

This is what a slide looks like once
developed. To view it successfully it is inserted into the viewer with a
plate that has a centre dividing line (this can be seen in the complete
set layout in the bottom picture), this helps the viewers eyes to separate
the two images.
The complete SKF-1 kit, with all
accessories. These kits are often sold, incomplete, on eBay.
It is worth making sure that all items are present. The instructions are
in Russian, but it is not hard to work out how to use it.
