Magnifying Glass In Wooden Box. Condition is "Used". Dispatched with Courier as photo glass some are chipped as photo I am not sure the history on these so selling as spares and repair could be some use to someone with more knowledge then me 6” large lenses 1.5” inch the small one
Photo 1 overall
Photo 2 'eyepiece'/prisms/singlets closeup
Photo 3 ditto
Photo 4 physically resembles a secondary mirror but not reflective
Photo 5 closeup of one of the "lenses" (identified by chip)
Photo 6 closeup of the other lens (identified without the chip)
Can someone clue me in here what I'm looking at, or what is this set for? My uninformed eye saw the large pieces of thick glass and thought 'mirror blank'.
No magnifying lens for visual inspection of things I've ever seen for sale is made of a singular, thick piece of 'glass'.
But the obvious answer I have in mind is these are two 6 inch optical plates/stages for inspecting things. But I've also seen a fair few of those for sale, of varying ages, and never have they been this thick...
I'm sure what it came with might be a hint, but the closer I look at the box the more homemade it looks. Even if its not a telescope blank, can someone remind me what type of glass it might be from its colour?
