All the surfaces are inclined precisely 45 degrees to the light path, and ALL, not some, of the light is reflected internally with no need of silvering whatsoever.

The monocular is Razor sharp and Crystal clear , made with the best lead glass from 1960s. This item is in the category "Cameras & Photo\Binoculars & Telescopes\Binoculars & Monoculars".
