Meller Optics, Inc. offers custom fabricated sapphire optics for use in aerospace and other critical applications requiring resistance to fast-moving dirt, temperature extremes, and high pressure.
- Curve radius tolerance of 0.5” to 2.5” with focal length accuracy of ±0.0005”, depending upon radius
- Impervious to water, most acids, alkalis, abrasion from fast-moving particulates, temperatures to 1,000°C, and pressures up to 10,000 psi
- Surface finishes from 60-40 to 40-20 scratch-dig, flatness held to 0.5 fringes of HeNe, and parallelism from 20 to 2 arc/secs., depending upon configuration
- Manufactured in 3/8” to 4” dia. sizes in varying wall thicknesses with ±0.001” tolerances in plano-convex, -concave, meniscus, and dome shapes, including custom edge finishes
