New, High Performance, Durable Polarizers for Projection Displays

From MOXTEK, Inc.
 

 
Wire-grid polarizers are now available for broadband visible applications. This type of polarizer is very attractive for projection display applications because of its high efficiency, high contrast, and extreme temperature and flux tolerance. However, using wire-grid polarizers as drop-in replacements in existing architectures, significantly limits the possible applications of this new polarizer type. As with conventional polarizers, wire-grid polarizers come in a sheet format, but they reflect one polarization rather than absorb it. Therefore, care must be taken in the system design to control this reflected light. Other significant design issues will also be highlighted in this paper. Applied Digital Optics, Inc. and MOXTEK will discuss design issues concerning the use of ProFlux™ wire-grid polarizers in the illumination stages for projection, as well as other suitable applications. Conceptual designs will be presented. The paper will review the specifications for the ProFlux™ wiregrid polarizers, identify classes of possible applications that are well suited to this new type of optical component, and present design examples of the illumination stages for projection display applications.
Products & Services
Optical polarizers are optical devices that can transform unpolarized or natural light into polarized light, usually by the selective transmission of polarized rays. Search by Specification | Learn more about Optical Polarizers
Optical windows are used to isolate different physical environments while allowing light to pass relatively unimpeded. Search by Specification | Learn more about Optical Windows
Linear polarizers transmit light waves along one axis and absorb them along the other. The transmitting and absorbing axes of linear polarization are oriented at 90 degrees to each other. Search by Specification | Learn more about Linear Polarizers
Plate beamsplitters are semi-mirrors, which reflect part of the incident energy (absorb a relatively small part) and transmit the rest. Some are neutral and some are spectrally selective. Search by Specification | Learn more about Plate Beamsplitters
