Index-matching fluids are liquids used to reduce or eliminate unwanted Fresnel reflections at interfaces between optical components by closely matching their refractive index to that of the solid material. This minimizes the reflectivity, which is proportional to ((n 1 n 2) / (n 1 + n 2)) 2, and. ty. matching approach a pragmatic alternative to zero-gap design. What Lucent, 3M, and other suppliers have discovered is To understand how an index-matching gel minimizes the that the secret to using index-matching gels is in the design of reflection light at the connection, consider the basic. Norland Index Matching Liquid (IML) 150 is a low viscosity liquid monomer used as an index matching media for temporary fiber slicing. Unlike silicone index matching liquids which are difficult to completely remove from a fiber end after use, IML 150 is easily removed using acetone.
