Refractive Index Of Acrylic Sheet

Below are files of complete refractive index and extinction coefficients.

Refractive index of acrylic sheet.

The optical properties of plexiglas sheet make it ideal for edge lighting applications. If the file is not available for download you can request our proprietary file by clicking request. Kpr 300 can also measure resin samples that cannot be processed and be measured. Each material in the database has refractive index listed as a function of wavelength over a range typically required for thin film thickness measurement.

Standard refractive index measurements are taken at the yellow doublet sodium d line with a wavelength of 589 nanometers. To make the most effective and efficient use of edge lighted acrylic shapes fabricators. With using refractometer kpr 300 we can know the relation between refractive index and wavelength δn δλ by multi wavelength measurement. Cargille acrylic matching liquid characteristics.

For a typical sample of acrylic the refractive index and extinction coefficient at 632 8 nm are 1 48899 and 0. There are also weaker dependencies on temperature pressure stress etc as well on precise material compositions presence of dopants etc. Conditions spec sheet temperature. 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. Refractive index 1 57 astm d 542 haze 1 0 astm d 1003 electrical dielectric constant 1 khz 2 6 astm d 150 dielectric 1 mhz 2 4 astm d 150 dielectric strength 410 v mil astm d 149 recycle code 2 polyethylene terephthalate glycol modified.
