Color Corrected Lens (CC-GPL) Technical Details

SPECIFICATIONS

  • 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

BENEFITS

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

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.
