Technical Details


  • Transmittance: up to 80%
  • Thickness: < 2mm
  • Available F-numbers: F/0.5 – F/100+
  • Smallest Grating Period: <2um at edge
  • Size: Up to 300 x 300mm sq
    • Round or arbitrary cut samples are custom
  • Patterning: Any lens/array shape possible
  • Larger custom lens sizes are available with additional NRE


Because of their unique phase manipulation mechanism and radically different fabrication, Color Corrected GPLs offer:

  • Any prescription can be incorporated
    • Spherical, Aspherical and cylindrical
  • Can be used for aberration correction
  • Low F-numbers available
  • Thickness is largely independent of lens F/# and size
  • Polarization dependent, with a positive or negative focal length controlled by the input polarization
  • Can work with any input polarization
  • Chromatic dispersion is compensated for three primary wavelengths

Additional Applications for Color-Corrected GPL

FAQs about our CC-GPLs

Q. Since GPLs naturally have negative color dispersion, is there a way to correct for that?
A. Yes. With multiple GPLs and polarization management, we do make a color corrected GPL (CC-GPL). Please see our technology page on this for additional information.

Q. Can you simplify my complicated lens system?
A. Yes. By using a combination of GPLs and CC-GPLs and potentially some standard lenses, you can correct aberrations, get rid of expensive optical materials and make the lens system shorter in length.

Some Questions to Consider

These are typical questions we like to ask when engaging you as a customer to help best assess and understand your needs and challenges.

  • What are the key issues with your current solution?
  • Describe the major optical challenges you are facing. Is it low efficiency? Is there a unique polarization? a difficult phase profile to work with? or something else?
  • Are there specific technology features (i.e., diffraction, polarization, retardation, wavefront, focus, opto-electronics, other) that you are interested in?
  • What are the characteristics of the light source you need to work with (i.e., polarization, bandwidth, collimation, intensity, coherence)?
  • What are the desired characteristics of the light at the output of the system?
  • Are there any specific tests, experiments, or prototypes that would best validate a solution for your problem?
  • What is the timeframe within which you need a demonstrated solution?
  • Are there any unique or challenging form factor requirements? Thickness requirements? Large active area requirements?
