7056 Borosilicate Glass Viewports

ANCORP’s 7056 borosilicate glass viewports are excellent general-purpose windows for observation within a vacuum chamber. Borosilicate glass has a low coefficient of thermal expansion and has high transmission in the visible range.

Borosilicate glass viewports are available with zero-length profile ConFlat (CF), ISO-QF (quick flange, KF, NW), and ISO-LF (large flange, ISO-K) flanges.
