 VISAR Anti Reflection, AR, Coating on Acrylic PMMA     

      

       VISAR 01 Acrylic is a multi-layer anti reflection, AR, coating produced by vacuum deposition. It is available on sheet acrylic, from 0.5mm to 8.0mm thick. It is also available as a one sided or two sided coated acrylic sheet. 

      Visiontek Systems is one of the leading manufacturers of sunlight readable PMMA + Anti-Smudge (AFP) coated acrylic, and is highly regarded for its quality products. Our company offers a range of AR coated products that are of a high quality at very affordable prices. We also provide custom solutions for our customers

     The VISAR 01 coating, like all multi-layer coatings, is susceptible to finger marking so it is recommended that users select the option of an anti fingerprint layer (AS) on the front surface. This hydrophobic layer has no significant effect on the optical performance but improves resistance to finger marking significantly.

 Function

 The sunlight readable function or AR coating comforts the working eyes, and the AFP (Anti-Fingerprint) coating prevents contamination from human contact. This product has been created for both industrial and consumer displays
