High Refractive Index

High Refractive Index

High refractive index (HRI) materials are materials with a refractive index higher than that of a standard material such as glass, water, or air. These materials have a wide range of uses, including in the production of optical lenses, optical fibers and waveguides, and optical films. HRI materials provide advantages such as better light transmittance, higher light refraction, and increased optical clarity. They are also used for thin film coatings and as components in optical systems. In addition, HRI materials can be used to improve the performance of solar cells, LCD displays, and imaging sensors. They are especially useful in the production of thin film coatings, as they allow for a greater amount of light to be refracted.
