Optics Polarizer

  • 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.

Polarizing Beam Splitters

  • 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.

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.

  • 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?
    We have products that range from deep UV to long wavelength infrared.

  • 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.

General

  • Does Moxtek offer encapsulation services?
    Yes. We specialize in encapsulation services, please contact us for more details.
  • What information is needed to send a quote?
    On the right-hand side of each product web page is a "Request a Quote" button. Clicking it presents a form with the required details (e.g. contact information, etc.) we need to create a quote. In the comments field of that form, you can include a brief description and the required dates and specifications of your request. Once we receive your information, we’ll respond promptly.

  • What is Moxtek's positions on the ʺConflict Mineral" issue?
    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.
