Paper Abstract

We have designed and fabricated the low-polarizing X-plate to increase the luminous throughput for LED projector. We calculate reflectivity characteristic of X-plate as a function of the wavelength at different angles of incidence from air of unpolarized light. A new way to design filter to control the title effect of thin film filters. The wavelength shift of the new design for reflected red filter and reflected blue filter at the angle of 45° ± 8° is 16 nm and 14 nm, respectively.
