    Thumbs up FS: New/Unused Fused Silica flat 50mm

    Rather difficult to find. Fused silica flats with double side (single, MgF2) coated.

    50mm dia 2mm thick.

    Have numerous possible uses as a filter (for UV lenses with 52mm filter) or a clear filter for "full spectrum" mods.
    Makes a fabulous protective filter for the UV-Nikkor 105/4.5 while allowing full transmission, for example.

    55 euros/piece shipped within the EU. If you are elsewhere, tough luck. Contact someone (not me) to buy it for you. Bank transfer preferred.

    1 piece per buyer. I have a limited quantity. It is a real bargain for those who know what this is.


    Parallelism arc minute <5 arc minutes
    Diameter Tolerance +0.0, -0.13mm
    Thickness Tolerance 0.25mm
    Surface Quality 20/10

    Grab them before I change my mind.

    The coating alone is worth the money!
