These sapphire windows are engineered to withstand extreme centrifugal forces while resisting the etching and fogging that often compromise standard optics. To assist with precision, each unit features a scribed arrow on the edge to indicate the optic axis, a design choice intended to simplify alignment during installation. The windows are manufactured to strict physical specifications, measuring 19.03 mm in diameter and 5 mm in thickness, with a 30-10 scratch-dig surface finish and chamfered edges for secure sealing.

Meller Optics is positioning these replacement parts as a direct, high-durability alternative for laboratory environments relying on Beckman Coulter equipment. Pricing for the sapphire replacements is available directly through the manufacturer’s Providence headquarters as they look to establish a wider distribution network for the product line.
