Zero length viewport 7056 glass, DN19CF

CF Zero Length Viewports facilitate observation or illumination of the interior of a vacuum chamber, ensuring monitoring of individual components or entire vacuum systems. The zero-length design provides an expanded, distortion-free viewing area.

These viewports utilize Corning 7056 glass, the industry’s most commonly used vacuum window material, guaranteeing both transparency and durability. Borosilicate glass is known for its low coefficient of thermal expansion and high transmission in the visible range.

These viewports are constructed as one-piece assembly, incorporating flanges made of Stainless Steel 304 for durability and resistance to corrosion.
