Providence, RI-based Meller Optics, Inc. has made available custom manufactured sapphire optics designed to withstand extreme environments in a variety of applications. Meller Custom Sapphire Optics are manufactured to specification for applications that require a clear, durable and chemically inert window, lens, cube or cover that is impervious to water and can withstand pressures up to 10,000 PSI (depending on configuration). Featuring drilled holes, slots, wedges, stepped edges for ease of assembly, elliptical edge shaping or metallization, these optics are ideally suited for use as viewports, instrument covers and wear surfaces in harsh environments. Sapphire optics are available in sizes and thicknesses ranging from 1/4” to 10” diameter and 1/2 mm to 1” thick, respectively, and are second only to diamonds in terms of hardness (Moh 9). They can be supplied with various types of A/R coatings, and flatness can be held to 0.5 fringes of HeNe, with parallelism from 20 to 2 arc/secs.
