Refractive Index Of Acrylic Sheet

Below are files of complete refractive index and extinction coefficients.

Refractive index of acrylic sheet.

With using refractometer kpr 300 we can know the relation between refractive index and wavelength δn δλ by multi wavelength measurement. There are also weaker dependencies on temperature pressure stress etc as well on precise material compositions presence of dopants etc. Standard refractive index measurements are taken at the yellow doublet sodium d line with a wavelength of 589 nanometers. Kpr 300 can also measure resin samples that cannot be processed and be measured.

To make the most effective and efficient use of edge lighted acrylic shapes fabricators. The table below contains links to refractive index data for common materials.

Many materials have a well characterized refractive index but these indexes depend strongly upon the frequency of light. For a typical sample of acrylic the refractive index and extinction coefficient at 632 8 nm are 1 48899 and 0. Cargille acrylic matching liquid characteristics.

The optical properties of plexiglas sheet make it ideal for edge lighting applications. This page shows the results of measuring the refractive index with three wavelengths d line c line f line of acrylic resin pmma molded aspheric lens.
