Abrasion Resistant Optical Windows feature anti-reflective coatings.
Press Release Summary:
August 11, 2011 - Custom-designed to meet user requirements, Abrasion Resistant Optical Windows are available with 3 different levels of anti-reflective coatings that meet various MIL specifications. Coatings maximize optical transmittance while eliminating image ghosting, protecting optical systems in both hostile and common environments. Typical applications include camera lens systems, telescopes, POP displays, menu boards, digital signage, and LCD screens.

ZC&R Coatings for Optics Now Offers a Family of Solutions for Abrasion Resistant Optical Windows
Press release date: August 9, 2011
Abrasion from common airborne particles such as sand or poor cleaning procedures applied to external optical surfaces can significantly degrade the optical system performance. Airborne chemicals such as hydrogen sulfide, nitric acid, sulphuric acid, carbonic acid, and other corrosive constituents of urban smog can, over time, produce staining and etching of exposed optical surfaces.
To counteract these harmful environmental effects, ZC&R Coatings for Optics provides three levels of protection:
Level 1 - Hardened anti-reflective (AR) coatings applied to conventional glass substrates for less hostile operating environments.
Level 2 - Hardened anti-reflective (AR) coatings on hard optical substrates for more challenging environments.
Level 3 - Hardened anti-reflective (AR) coatings on sapphire laminated substrates for the most hostile operating conditions.
Level 1 coatings are the most economical, provide superior optical performance over most spectral ranges, offer superior abrasion resistance in comparison to conventional windows, and are available in a variety of sizes including large apertures up to 10" in diameter.
Level 2 coatings are moderate in cost, provide increased abrasion resistance, while also offering significant improvement in resistance to corrosive chemical exposure, have superior optical performance over most spectral ranges, and are available in a variety of sizes including large apertures up to 10" in diameter.
Level 3 coatings provide maximum resistance to abrasion, significant resistance to corrosive chemicals, while also providing enhanced protection from ballistic damage with superior optical performance over most spectral ranges. Level 3 coatings are available in apertures up to 6" in diameter.
Typical applications include:
Camera lens systems
Point-of-purchase (POP) displays
Anti-reflective (AR) coatings provided by ZC&R meet the following MIL specifications:
AR coatings from ZC&R Coatings for optics will extend the service life of optical window systems while enhancing optical clarity and viewability. In addition, the coatings provide protection from weather and deterioration from chemical attack.
