Demountable viewport on a KF40 flange with UV grade fused silica optic

Demountable viewport for high vacuum systems allowing users to change optics without having to replace the complete viewport, which saves money, and is very useful if optic damage is likely, for example, in laser applications

Constructed from stainless steel 304L (1.4307) with an aluminium alloy retainer
Can be installed on standard KF vacuum ports, no special adaptors or fittings needed
UHV cleaned and helium leak tested
Typical lead time 4-6 weeks
Optic materials available: borosilicate glass, sapphire, zinc selenide (ZnSe), magnesium fluoride (MgF2), barium fluoride (BaF2) and calcium fluoride (CaF2). Other materials may be supplied on request.

Different sizes available on request.
