For a typical sample of acrylic the refractive index and extinction coefficient at 632 8 nm are 1 48899 and 0.
Refractive index of acrylic sheet.
Each material in the database has refractive index listed as a function of wavelength over a range typically required for thin film thickness measurement.
When refractive index surface reflectance and absorbance of the sheet are known the designer can create displays that appear to be self illuminated.
Below are files of complete refractive index and extinction coefficients.
Cargille acrylic matching liquid characteristics.
The optical properties of plexiglas sheet make it ideal for edge lighting applications.
There are also weaker dependencies on temperature pressure stress etc as well on precise material compositions presence of dopants etc.
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.
Standard refractive index measurements are taken at the yellow doublet sodium d line with a wavelength of 589 nanometers.
Many materials have a well characterized refractive index but these indexes depend strongly upon the frequency of light.
To make the most effective and efficient use of edge lighted acrylic shapes fabricators.
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.
Conditions spec sheet temperature.
Kpr 300 can also measure resin samples that cannot be processed and be measured.
