CLAREX Textured, Non-Glare Acrylic Sheets (NG)
Optimizes display readability by diffusing reflections.
Non-Glare Texture is also commonly referred to as Anti-Glare, AG, & Reduced-Glare. The CLAREX Non-Glare (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 Non-Glare 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 Non-Glare 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 hard-coating (6-8H Pencil Hardness) to the non-glare surfaces without filling in the texture.
Non-Glare surfaces could be added to one or both sides, and don’t necessarily have to match.
Note: If you hold one of these Non-Glare filters up and look through it, it will appear hazy. That haze goes away as the gap between the Non-Glare 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.
