Benefits of Non-Glare (NG) Anti-Reflection (AR) Glass and NG/AR Glass

Anti-Reflection (AR) coated glass helps diminish surface reflections while increasing light throughput or brightness of the viewed image over moderate wavelength and angular ranges. Standard AR coated glass is not diffusive and is therefore able to maintain the highest levels of image resolution and clarity.

 

Non-glare (NG) glass is etched to produce uniform and evenly diffusive surfaces that disperse reflected light, preventing glare even at extreme angles. The lower the gloss level, the more diffusive the surface and the less glare but with some sacrifice of resolution and throughput efficiency of the viewed image. Anti-reflection coated NG glass (NG/AR) combines a bit of both; improvement of throughput efficiency, reduction in photopic specular reflectance of NG glass alone and retention of diffusive surfaces for reduced glare over large angles. Abrisa Technologies offers all 3 options and custom solutions to fit your needs.
