Optical coatings

Low Refractive index coatings

Inkron’s standard low refractive solutions are particle free and provide excellent optical properties; scatter free high transmission and low haze. Certain grades are designed for gap filling applications needed for enforcing NIL structures or to achieve the refractive index difference necessary in some optical structures.

High Refractive index coatings

Inkron’s standard NIL processable high refractive index (RI) products are optimized for Nano Imprint Lithography (NIL) but may be used also as an overcoat. Special care has been taken to maximize the optical and process properties. It is possible to adjust the formulation to meet the specific refractive index and thickness targets.
