Vacuum Viewports
REFLEX Analytical offers a series of vacuum flanges and viewports. The standard flanges are Varian Conflat 954-5076, 954-5078 and 954-5135. Clear apertures range from 0.465" to 2.16" with larger diameters available upon request. The flange and viewport assemblies incorporate ultraviolet, visible and infrared transmitting window materials such as BaF2 Barium Fluoride, CaF2 Calcium Fluoride, SiO2 Fused Silica, Ge Germanium, KBr Potassium Bromide, LiF Lithium Fluoride, MgF2 Magnesium Fluoride and ZnSe Zinc Selenide.

Each assembly offers a guaranteed vacuum tight seal (vacuum tested 10 -8cc/second on a Helium leak detector, customer verified UHV performance at 10 -12cc/second) and generally bakeable to 120C with a few exceptions dependent upon window material characteristics. The vacuum assemblies provide for either 6 or 8 mounting holes and are accompanied with copper gaskets and bolting hardware.
