Huntington Bellows Sealed Viewport Shutters are manually operated rotary shutter assemblies incorporated into a double sided VAC-U-FLANGE® flange. Viewport Shutters are critical to preserving the light transmission capabilities of viewports especially in vacuum coating applications where material can become deposited on the optical substrate. The Shutter can be locked in a closed position to prevent the buildup of material on the viewport glass, then opened for viewing after the process. It can also be locked in any open position in it’s swing of travel. Protect your investment in expensive or hard-to-replace viewports with Huntington Viewport Shutters.

● PROTECT VALUABLE VIEWPORTS

The flange to which the door is hinged mates with an identical flange on the chamber or load lock. A captured Viton® O-ring in the face of the door provides the door seal when it is closed and locked.

"Ceramic to Metal Adapters (Vacuum Breaks and Envelopes) Huntington’s Ceramic-to-Metal adapters allow for high-voltage insulation for flange to flange connections in applications requiring high and ultra high vacuum insulated mounting. Pressure range is 1 x 10-9 Torr-L/sec. He. with bakeout temperatures of 400°C for VAC-U-FLANGE® models and 200°C for SPEED SYSTEM models. The ceramic material is 90% Aluminum oxide joined to a Kovar® sleeve, which is then joined to the stainless steel flange using industry standard ultra high vacuum brazing techniques."
