Request InfoFiber Optic Center Inc.High Refractive Index Coating from Fiber Optic Center Inc. is designed for optoelectronics, LEDs and emissive displays. The coating is an optical polymer dissolved in an evaporative solvent that can be applied by simple methods such as dip, spin coating, drawdown, printing and more. Upon drying, it creates a hard, durable, polymer coating with a refractive index of 1.64. The polymer contains no metals, and the product contains no nanoparticles. The standard concentration leaves behind an approximate 20-μm-layer coating thickness using a single-dip coating process.
