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.
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.
