FUSED QUARTZ TELESCOPE MIRROR BLANKS - 6" Diam 1" Thick - NOS :
These are NOS genuine fused quartz 6x1" blanks, fused as in made from actual quartz crystals. The melt zones can be seen in some of the pics or under polarized light (pics available on request). They are high end blanks, beautifully finished and polished around 5-10 waves flat both sides (I've checked them all).
Due to how they are made they necessarily include small bubbles but the surfaces are not affected and only small bubbles appear anywhere near the surface SFAIK. I'll ship the best ones of the lot first.
Excellent for a high performing mirror or bino, 3 could make into some very nice flats with some work.
Asking $120 each, will combine shipping for more than one.
Thanks for looking!
