Refractive Index Of Plastic Sheet

Many materials have a well characterized refractive index but these indexes depend strongly upon the frequency of light.

Refractive index of plastic sheet.

There are also weaker dependencies on temperature pressure stress etc as well on precise material compositions presence of dopants etc. Conditions spec sheet n absolute. Sheet 1 is placed on top of sheet 2 and a laser beam is directed onto the sheets from above so that it strikes the interface at an angle of 26 5 with the normal.

Three sheets of plastic have unknown indices of refraction. Standard refractive index measurements are taken at the yellow doublet sodium d line with a wavelength of 589 nanometers.

Poly methyl methacrylate pmma also known as acrylic acrylic glass or plexiglass as well as by the trade names crylux plexiglas acrylite astariglas lucite perclax and perspex among several others see below is a transparent thermoplastic often used in sheet form as a lightweight or shatter resistant alternative to glass the same material can be used as a casting resin or in inks.
