They filter out one polarization state, and let another through.

Inorganic materials (aluminum Nanowires^® on glass, fused silica, or silicon substrates).

Silicon, fused silica, and display grade glass. Others possible upon request.

Yes. We do many non-standard coatings. Lead times may be longer to meet unique requirements.

Our inorganic products are designed for high temperature and high flux conditions similar to what is needed for light engines in projectors and laser systems.

We use 200mm diameter wafers with a 180mm diameter active area. We can cut polarizers from a 180mm diameter circle.

PBS02A uses 0.7mm display grade glass, such as Eagle XG. PBF02A uses Borofloat ^TM 1.6mm thick. Borofloat creates a flatter product because it's a polished wafer on a thicker substrate.

7x7mm is the smallest size a PBF/PBS/PPL can be cut, with a tolerance of +/-0.2mm for both the X and Y directions. 4x4mm is the smallest that can be cut, but there is no allowance for edge exclusion.

Yes.

PBS02A and PBF02A are both optimized for AOI=45 degree, and PPL is optimized for AOI close to 0 degree. As small as 4x4mm can be cut with some modification of the clear aperture and edge exclusion requirements.

The difference is the size and number of the defects allowed on the finished part. Defect size ranges from 1mm for optical grade 4 and 150 microns for visual criteria grade 0.

Our standard products are about 170nm thick.

Substrate selection can contribute to the final price. The thick flat substrate is usually more costly than the 0.7mm substrate due to higher manufacturing costs.

S-polarized light should have a wave oscillation parallel to the nanowires.

Moderate light levels mean the light level that will maintain the flatness of the PBF and will not cause a distortion in the image because of thermal expansion. We've never had a problem with any applications that include thermal expansion induced distortion. We can take the heat.

Yes. We specialize in encapsulation services, please contact us for more details.

Never do we knowingly purchase conflict minerals. We purchase the following minerals from conflict free smelters: tin, tantalum, tungsten, and gold. We require our suppliers to purchase these metals from conflict free smelters, as well.
