Q: What are the disadvantages of Polarization Directed Lenses?
A: For optimal efficiency, these lenses necessitate incoming light to be circularly polarized, demanding careful setup and potentially additional polarization optics in the optical design. Additionally, as these lenses function as gratings, they exhibit significant chromatic aberration when employed with broadband illumination. It is advisable to limit the spectral bandwidth of the illumination to achieve the best results.
