- Retardation Bands: fully customizable between 400-4000nm
- Topological Charges Available: 1, 2, 3, 4, 8, 16, 32
- Other custom charges possible
- Broadband Illumination: Yes (similar ranges as our achromatic MTRs)
- AOI: Up to +/-20˚
- Center wavelength options: Fully customizable from 400-4000nm
- Patterned/louvered domains: nearly any pattern, with resolution down to <5 µm

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
