Featured inquiry:

We have urgent requirement of UHV compatible viewport window flange. Viewport window should be MgF2 with viewing dia of 25mm and 2mm thick. This window shall be sealed on to stainless steel CF flange of size and weight which are very minimal (even if it is non standard size with minimum possible thickness).
Another requirement is similar MgF2 window fused onto a weldable flange (minimum size and weight).
Request you to provide technical info ( dimensional details) and budgetory quote.
