(Meller Optics: Providence, RI) -- Custom-fabricated sapphire prisms that are ideally suited for use in instruments that measure moving liquids and slurries in real-time have been introduced by Meller Optics of Providence, Rhode Island.

Meller sapphire prisms feature Mohs 9 hardness to provide the wear resistance necessary for any instrument using light refraction as a measurement technique. Polished to 20–10 scratch dig or better on rectangular surfaces, they can be manufactured in sizes from 1/2 in. to 4 in. on each leg of a right angle, with custom angles and a tolerance of 3 to 10 minutes.

A far more durable replacement for glass or quartz, Meller sapphire prisms are chemically inert and designed for use in demanding fluid-measurement applications. Second only to diamond in terms of hardness, these prisms are offered in various equilateral, right-angle, trapezoid, and triangle configurationsand are fabricated to OEM specifications.

Meller sapphire prisms are priced according to configuration, size, and quantity. Price quotations are available upon request.
