Project: nanoCLEARA new in-mold AR coating product that enables AR lens production with the quality, speed and cost of table top lens casting.

Product OverviewInnovative, low cost, multilayer, thin film anti-reflective coating system based on: Unique, spin applied liquid

chemistries The coating’s optical and

mechanical properties are engineered using nanomaterials

Low cost, low complexity hardware enables retail store deployment

Capital equipment costs are much lower than current vacuum systems

Enables 1 hour service for AR coated Cast to RX ODC Lenses

•Alternating layers of high and low index thin films

•Film thickness ~100nm

•Tolerance ~+/- 5nm

•Minimum of three layersLens

Anti-Reflection and Nanomaterials

Material Mohs Hardness Refractive Index

Al2O3 9 1.62 @ 600nm

SiO2 7 1.46 @ 600nm

TiO2 6 2.2-2.7 @ 550nm

• An anti-reflective coating is achieved by depositing thin films of alternating refractive indexes

• By engineering the refractive indexes and thicknesses of these films, visible reflections are reduced and transmission is improved

• Nano-scale additives must be used to avoid transmission losses and scattering that occur with larger particles

Nanomaterial benefits:

• Increased ability to engineer refractive index

• Improved mechanical performance
