CLAREX NonGlare Textured Acrylic (NG)
Optimizes display readability by diffusing reflections
NonGlare Texture is also commonly referred to as AntiGlare, AG, & ReducedGlare. The CLAREX NonGlare (AG) Textures are available from low to high gloss levels, and have been specifically developed for different applications. The medium gloss levels (30-70) are most common and generally used in front of flat panel displays to help eliminate the glare from a bright environment. The higher gloss (>70) levels are useful if there is a large gap between the display and the NonGlare filter. The highest gloss levels (90+) can be used to eliminate Newton Rings without creating much haze. And the lowest gloss textures (<10) are used for light diffusion and aesthetics.
The NonGlare textures are cast into the sheets. They are not coatings based. So the textures are controlled and repeatable. And CLAREX is unique in that the factory is able to apply their standard Hardcoating (6-8H Pencil Hardness) to the nonglare surfaces without filling in the texture.
NonGlare surfaces could be added to one or both sides, and don’t necessarily have to match.
Note: If you hold one of these NonGlare filters up and look through it, it will appear hazy. That haze goes away as the gap between the NonGlare filter and the image behind it is reduced, so it works great directly in front of a display. However, it is not suitable for use in front of a camera or other imaging/sensor application. If reflections are causing you issues in your imaging application, check out the Anti-Reflection coated sheets.
