Reflective index meaning

WebIntroduction. 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. 1,2 With the need for mechanical … WebThe sensitivity of a typical TOFS is 0.0001 RIU (Refractive Index Units) meaning the device is capable of detecting a 0.0001 change in refractive indices. This allows TOFS to be sensitive in molecular-level interactions. A tapered region or the sensitive area of a TOFS is obtained by stretching single-mode fiber cables to desired dimensions.
