What is a Geometric Phase Lens?

A Geometric Phase Lens (GPL) is an LCP-based thin-film that functions like a volume lens or lens array, but with special features (polarization directed flat lens).

How It Works

The desired lens phase profile is encoded directly into the local orientation of the optical axis. Circularly polarized light takes on this phase profile directly through the geometric phase (also called the Pancharatnam-Berry phase) effect.

FAQs about Geometric Phase Lenses

Q. Can you reduce the weight of my large optical elements?
A. Yes. Our optics are thin films that have very little weight. Even large size films are a fraction of the weight and thickness of traditional optical elements.

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.

Q. Can you make a thin-film with a difficult phase profile without expensive and limited diamond turning fabrication?
A. Yes. This would just be a custom GPL solution.

Q. Can you combine multiple lenses and optics in a single element?
A. Yes. Because our films are flat, we can fabricate and laminate them together in a single monolithic component.

Q. Can you correct for optical aberrations in a set of lenses?
A. Yes. Our GPLs can be customized to add aberrations for correction.

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?
