High transmittance (HT) polarizers are characterized by a transmittance up to 96% and high contrast ratios over 10,000:1 within the given spectral range.
They are available in standard thicknesses of 0.2 mm, 0.27 mm and 0.5 mm. OEM quantities are shipped in dimension matched waffle packs.

1) Laminated thicknesses can be found in the specification and on request.
The contrast ratio is defined to be k1:k2, where k1is the transmittance of a polarized beam passing the filter and k2 is the transmittance of a polarized beam blocked by the filter.
