By the use of dichroic dye film, a good linear polarization can be obtained in a wide range. The sheet polarizer can be used in the basic polarization experiments which do not require high precision, and adjustment of the light intensity.

◦Since the polarizing film is sandwiched between the protective glass plate, it hardly gets scratched, and dirt can be wiped off.
◦Because it is mounted in the frame, the handling of the optics and mounting in the holder is easy.
◦There are products offer for three wavelength ranges, Visible, UV and Near Infrared.
◦Since the anti-reflection film is applied on both sides the stray light and back reflection to the light source is reduced.

Guide

▶A sheet polarizer other than the size listed on-line or in our catalog, or without the frame are also available.
▶If there is a request for specific transmittance, extinction ratio or wavelength range, please contact our Sales Division.
▶Glan Thompson prism (GTPC) with high transmittance and high extinction ratio are also available.
W3450
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶A change in the incident angle may also change the extinction ratio of the linearly polarized transmitted light.
▶Separation angle will vary depending on the wavelength. Please confirm the wavelength characteristic graph for separation angle.
▶Because of natural calcite crystals, there are individual differences, and variations in quality.
