 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. 

Because of the chemical and physical characteristics of acrylic, it is necessary to support the VISAR 01 coating by interposing a 7 to 10 micron thick hard coated layer. This gives the acrylic a  more physical durability.

     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.

  A section through a preferred VISAR product is shown below.
