Materials for High and Low Refractive Index Coatings

Refractive index (RI or n) is of critical importance for photonics applications such as optical waveguides and ophthalmic devices. Based on their unique refractive index characteristics and good optical clarity, polymeric materials are also used as anti-reflective coatings for solar cells, displays and contact lenses.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
