BENEFITS

  • Due to their simple fabrication and many degrees of design freedom, VPRs are ideal for:
  • Patterned Retardation (louvers or other patterns)
  • Multiple Charges
  • Precision Retardation
  • Smallest Central Defect

Additional Information

Vortex retarders generate nondiffracting, or Bessel, beams, which have been demonstrated to enlarge the trapping region and the kinematics of optical tweezers and for transport and guiding of microspheres.

  • Other Applications
  • Sub-wavelength Resolution Nano-optics
  • Control of Bose-Einstein Condensates
  • Quantum Informatics

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?
