Service prepares windows for assembly into viewports.

Viewport Optics Preparation Service provides ground window blank to customer for metallization and then performs final polishing, without disturbing metallization, once it is returned. Capable of working with ZnSe, ZnS, CaF2, MgF2, as well as other materials, offering includes windows from Ã-¼-3 in. OD and 2-10 mm thick in stepped- or straight-wall configurations. Surface finishes from 10...

Sapphire Windows withstand pressures to 10,000 psi.

Custom fabricated windows, used as viewports, protective covers, and front surface optics, are suitable for use in hostile environments. Moh 9 surface hardness provides optimal abrasion resistance, and construction is impervious to water, acids, alkalis, and harsh chemicals to 1,000Ã-ºC. Available in sizes from Ã-¼-10 in. dia, with thicknesses from Ã-½ mm to 1 in., windows can be...

Sapphire Windows suit navigation and targeting systems.

Custom fabricated sapphire windows, available in sizes up to 18 in. in dia. x Ã-¼ in. thick, feature transmitted wavefront to Ã-¼ wave, parallelism to 2 arc-sec, and 70:1 aspect ratio. Manufactured to end-user specifications, products have Moh 9 surface hardness for optimal abrasion resistance. Features include surface finishes to 60-40 scratch-dig as well as resistance to water, acids,...

Sapphire Waveplates extend polarization control to infrared.

Custom-manufactured Sapphire Waveplates are suited for any laser that transmits 2.8-4.7 mm. Offered in Ã-½- and Ã-¼-wave, in both multiple and zero order configurations, they can be thinner than quartz waveplates because of intrinsic Moh 9 hardness. Featuring 10-5 scratch-dig surface quality and less than or equal to 1 arc/sec parallelism, waveplates are offered in 10-30 mm dia sizes with...

Laser Mirrors are made from silicon or molybdenum.

CO2 Laser Mirrors, for 25 to 200 W industrial lasers, are available in -½ to 1-½ in. OD sizes. Silicon mirrors feature average reflectance >99.5 to 99.7% @ 10.6 -µm and 45-° AOI, while molybdenum mirrors provide 98% average reflectance, and are more durable for use in applications that require frequent cleaning. Mirrors made from silicon can be provided with enhanced silver, copper, and DMBR...
