    Fiber Optic Center, Inc. Introduces High Refractive Index Coating for Optoelectronics, LEDs, Emissive Displays, AL-2264

    New Bedford, MA, USA, July 7, 2017– Fiber Optic Center, Inc., (FOC), an international leading distributor specializing in helping their customers make the best cable assemblies in the world, introduces High Refractive Index Coating for Optoelectronics, LEDs, Emissive displays, AL-2264

    FOC introduces a new product, an optical polymer dissolved in an evaporative solvent that can be applied by simple methods, i.e. dip, spin coating, drawdown, printing, etc. Upon drying it creates a hard, durable, polymer coating with a refractive index of 1.64. This polymer contains no metals, and the product contains no nanoparticles. The standard concentration leaves behind an approximately 20u layer coating thickness (using a single dip coating process). Coating thickness is easily reduced by diluting the standard concentration with the compatible solvent. The solvent is easily removed by baking at 100°C for 15 minutes.

    Optically clear, high refractive index coatings can be used to improve the performance of light gathering/dispersing devices.  Many solid state optical devices, i.e. imaging/optical sensors, emissive displays, LEDs, are made of light emitting semiconductors with significantly higher refractive indices (>2) than air (1.0). Light is partially reflected when it encounters a sudden difference of refractive index. Light transmission at such boundaries is improved with a layer of an intermediate refractive index material, thus improving the optical efficiency of the device – effectively raising the numerical aperture (NA) of the optical system. For semiconductors and air, that desirable refractive index is in the >1.6 range. Additionally in this case, the ‘air’ side of the coating directly contacts the environment and must be protective: hardness and durability are required; chemical resistance is a plus.

    For questions on specific applications for AL-2264, Randall Elgin, Technical Manager for Specialty Products at FOC can be reached 508-717-8376 or randalle@focenter.com.
