PROVIDENCE, R.I., Feb. 4, 2015 — Meller Optics UHV Sapphire Viewport WindowsCustom fabricated sapphire viewports and sight windows for ultrahigh vacuum (UHV) systems and process machinery are available from Meller Optics Inc.

They resist chemicals (including fluorine to 300 °C) and most acids, and are impervious to fast-moving water and particulates such as blowing dirt and sand.

Available in a variety of configurations and sizes from 0.25- to 10-in. in diameter and 0.5 mm to 1 in. thick, the windows can be fabricated with stepped edges and elliptical edge shaping, holes, slots and wedges for mounting, and include antireflection coatings.
