Custom fabricated sapphire windows and lenses of about 10in diameter in size have been launched by Meller Optics. This sapphire material has the ability to remit from the UV to the IR and is resistant to most chemicals, impurities, water, and sand. These are appropriate for utilization as protective optics in refractometers, weapons, and cameras and as machine viewports due to its clear and sturdy property.
Sapphire Windows From Meller Optics Are Clear as Glass in Large Sizes
Meller Sapphire Optics, based on the diameter to thickness aspect ratio, can be created in sizes up to 10 in diameter that makes chemicals, water, and accelerated particles impenetrable. Additionally, these are clear like glass and resemble diamond in hardness (Moh 9), and can withstand up to 1,000°C, and are transmitted from the UV to IR, ranging from 270 nm to 4.7 µ.
Meller Sapphire Optics offer flatness to 1/10th wave in the visible and < 2 arc sec. in./in. parallelism, end products from 60-40 to 40-20 scratch-dig, based on construction and size, and are ideal for use as viewports, and as protective front surface optics. Sapphire windows and lenses are employed as machine inspection windows and as viewing devices in weapons, cameras, and refractometers.
Established in 1921, Meller Optics supplies high quality optics to laser, medical, defense, and industrial markets since 90 years. The company is capable of polishing and grinding of rigid durable materials including sapphire and ruby, and has also provided improved low-cost and accelerated end- processes for optical materials including zinc selenide, germanium, laser glasses, fused silica, silicon, ceramic materials, and fluorides. These are arranged into domes, windows, lenses, substrates, and prisms. Furthermore, the company is a supplier of fine Gugolz optical polishing pitch and Microlux Alumina polishing abrasives.
