Optiguard WET AR surface treatment is a cost effective alternative to the exclusive vacuum deposited Optiguard DRY AR. The performance of WET AR regarding light transmission and reflectance is good.
It has a accurate colour reproduction and is easy to clean, furthermore it has great chemical and abrasion resistance.
It is an excellent choice for a wide range of applications e.g. large window applications like information displays.

The Vacuum AR treatment is also available in a Marine grade. This gives the material excellent salt water Resistance and high performance. The anti-reflection coating on the material is applied to both sides and enables full readability – even in the brightest direct sunlight.
The Optiguard™ AROL treatment has great saltwater resistance. Current applications include use in naval aircraft carriers, for stopping unwanted internal reflections when helping guide approaching pilots to the vessel.
