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

3. Product Overview Innovative, 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

4. Anti-Reflective Stack • Alternating layers of high and low index thin films • Film thickness ~100nm • Tolerance ~+/- 5nm • Minimum of three layers Low Index High Index Mid Index Hard Coat Lens

5. Material Mohs Hardness Refractive Index Al2O3 9 1.62 @ 600nm SiO2 7 1.46 @ 600nm TiO2 6 2.2-2.7 @ 550nm Anti-Reflection and Nanomaterials • 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
