Data Sheet Hybrid Wire Grid Polarizer & Thin Film Dichroic Filter Bookham and Moxtek, Inc. have collaborated to produce a hybrid Optical Wire Grid Polarizer and Thin Film Dichroic Filter combined on a common glass substrate and specifically designed for projection devices. The Bookham AED coating technology produces dichroic filters with industry leading performance and quality. Combined with Moxtek’s best in class ProFluxTM wire grid polarizers, the hybrid dichroic/polarizer provides an unbeatable combination of price and performance. Product Features: • The Polarizer and Dichroic Filter combination will replace each of the two separate elements in a standard system • Improved optical efficiency with less optical surfaces • Reduces the cost of an extra optical component and manufacturing assembly process 1 ProFluxTM polarizers are superior to all other normal incidence polarizers • Operate without degradation at high heat and light levels. • Operate at acceptance angles of ± 20º without depolarization of the skew rays and without compensation films. • Operate without degradation in typical consumer display environments. • Operate in combination with ProFluxTM beam splitters enabling system contrast of >10,000:1 ProFluxTM polarizers are recommended for use as prepolarizers and analyzers and in polarization recovery products with incident angles less than 20º. They may be ordered in any rectangular size from 10mm x 10mm to 90mm x 90mm. Smaller sizes, other shapes (such as circles and triangles) are available as special orders. In order to provide optimum application performance, ProFluxTM polarizers are available with various combinations of high contrast and high transmission.

The size of the cone depends upon the f/number of the system. Most systems us a cone half angle of less than 20º. The ProFluxTM polarizer performance changes very little with angle of incidence, resulting in uniform system performance over the aperture. This is illustrated in the typical off-axis 1/2 angle performance graphs of transmittance and contrast shown below.
