FAQ - Optical Polarizers
-
How do polarizers work?They filter out one polarization state, and let another through.
-
What are your polarizers made of?Inorganic materials (aluminum Nanowires® on glass, fused silica, or silicon substrates).
-
What other substrates can be used?Silicon, fused silica, and display grade glass. Others possible upon request.
-
Is it possible to customize the AR coating (or other types of dichroic coating) depending on our specifications?Yes. We do many non-standard coatings. Lead times may be longer to meet unique requirements.
-
Why would I choose your product over a polymer polarizer?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.
-
What is the largest size you can cut for a polarizer?We use 200mm diameter wafers with a 180mm diameter active area. We can cut polarizers from a 180mm diameter circle.

What's the difference between your PBF02A and PBS02A?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.
-
What's the smallest size your PBF/PBS/PPL can be cut into? What's the tolerance?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.
-
Do you offer only 1.6mm thickness for PBF02A?Yes.
-
What is the difference between the PBS series (PBS and PBF) and the PPL series?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.
FAQ - General Optics
-
How do visual criteria grade 0, 1, 2, 3 and 4 differ from each other?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.
-
What are the special handling requirements associated with your products?Where relevant, each product web page contains a downloadable datasheet with that information.

How do you package your polarizers for shipment?We ship our polarizers in a clamshell container that protects against damage during the shipment process.
-
What is the optics product warranty?Each product web page contains detailed warranty information.
View Optics Products Limited Warranty > -
How thick are your nano wires?Our standard products are about 170nm thick.
-
Does the cost relate to the thickness (0.7mm or 1.6mm)?Partially, the thick flat substrate cost more than the 0.7mm substrate because the thick substrate is polished.
-
From a cost standpoint, do you have a recommendation on the most optimized cutting size?The smaller the better. Leave at least a 1-2mm edge exclusion around the part.
-
What are your wavelength ranges for polarizers?
-
Can the flatness be better than 3 waves/inch?The Borofloat and fused silica materials can be polished to achieve 1-4 waves reflected flatness, depending on the part size, minimizing distortion in display imaging. Flatness is more difficult for larger parts. Very small part reflected flatness can be below 1 wave per inch.
Transmitted wave front error (TWE) is less than 1/10 wave. -
How should I orient the wires of the beamsplitter?S-polarized light should have a wave oscillation parallel to the nanowires.
-
What does ʺmoderateʺ mean as referred to in Moxtek presentation files?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.
