Refractive Index Of Acrylic Sheet

The optical properties of plexiglas sheet make it ideal for edge lighting applications.

Refractive index of acrylic sheet.

Conditions spec sheet temperature. Standard refractive index measurements are taken at the yellow doublet sodium d line with a wavelength of 589 nanometers. If the file is not available for download you can request our proprietary file by clicking request. Cargille acrylic matching liquid characteristics.

Data expressions for n csv comma separated txt tab separated full database record optical transmission calculator. Below are files of complete refractive index and extinction coefficients. The table below contains links to refractive index data for common materials. There are also weaker dependencies on temperature pressure stress etc as well on precise material compositions presence of dopants etc.

Kpr 300 can also measure resin samples that cannot be processed and be measured. 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. Each material in the database has refractive index listed as a function of wavelength over a range typically required for thin film thickness measurement. To make the most effective and efficient use of edge lighted acrylic shapes fabricators.

When refractive index surface reflectance and absorbance of the sheet are known the designer can create displays that appear to be self illuminated. For a typical sample of acrylic the refractive index and extinction coefficient at 632 8 nm are 1 48899 and 0.
