Sapphire Viewports

Sapphire has a broad transmission range from UV to mid-IR and is excellent in harsh environments and high temperatures. Sapphire is durable, scratch resistant, birefringent, and has a low coefficient of thermal expansion. ANCORP offers zero-length UV grade sapphire viewports in ConFlat (CF) and ISO-QF (Quick flange, KF, NW) flange sizes for use in high and ultra-high vacuum (UHV) applications.
