Sapphire Optics withstand UAV hard landings.

October 22, 2014

Featuring Moh 9 hardness, UAV Sapphire Optics resist scratching from sand, dirt, and hard landings. Optics are as clear as glass and transmit from 270 nm to 4.7 microns. Flatness can be held to 1/10th wave in visible and <2 arc sec in/in parallelism, with surface finishes from 60-40 to 40-20 scratch-dig. Available from 0.25–10 in. diameter, products are suited for use as outboard protective optics for imaging sensors and can be custom fabricated as lenses, windows, and domes. Read More

Hydrophobic Windows suit harsh and humid environments.

May 16, 2014

Designed to resist liquid absorption or wetting, TECHSPEC® Hydrophobic Windows utilize proprietary hydrophobic surface that causes liquid to form droplets on contact, rather than be absorbed or spread across surface. Anti-reflective coatings provide less than 0.4% reflection per surface from 425–675 nm. Available in 7 models from 5–75 mm diameter, windows exhibit contact angles of greater than 107° and maintain contact angles of greater than 100°, even after moderate surface abrasion. Read More

Hard Sapphire Windows protect sensors/cameras from particulate.

April 30, 2014

Providing protective surface for sensors and cameras exposed to high-speed particulates, custom Meller Sapphire Windows are as clear as glass and exhibit Moh 9 hardness. Various configurations and sizes up to 10 in. dia are possible depending on diameter to thickness aspect ratio. Featuring transmission from UV to IR (270 nm to 4.7 microns), windows offer flatness to 1/10th wave in Vis and < 2 arc sec in./in. parallelism with finishes from 60–40 to 40–20 scratch-dig. Domes are also available. Read More

Protective Sapphire Windows are durable and scratch resistant.

February 13, 2014

Available for 1 micron optics, Laser Research Fiber Laser Sapphire Windows act as debris shield replacements with Moh 9 hardness and reduce frequency of required lens changes. Available sizes range from 1–2 in. and withstand steel splatter, flash, and debris. Featuring 10-5 scratch-dig finish, 1/4 wave flatness, and A/R coatings on both sides, windows provide >99.5% transmission @ 1.07 microns with >90% @ 650–670 nm. Fused silica UV grade windows coated on one or 2 sides are also offered. Read More

BaF2 Windows provide high transmission without AR coatings.

January 23, 2014

Suited for such applications as IR spectroscopy, TECHSPEC Barium Fluoride (BaF2) Windows offer wide broadband transmission extending from deep UV to LWIR (200 nm to 14 μm). Barium Fluoride's 1.48 index of refraction promotes transmission without requiring anti-reflection (AR) coatings. Supporting use up to 800°C in dry environments, 5–50 mm dia windows are made from optical fluoride resistant to high energy radiation and have 82 Knoop hardness. Read More
