Meta patents lens that splits light into red, green, and blue
Meta describes a thin optical lens made of stacked liquid crystal layers that bends light differently for red, green, and blue colors. The design allows most other light to pass through unchanged, keeping the lens mostly transparent.
In the filing’s own words
An optical system includes a Pancharatnam-Berry Phase (PBP) lens configured to diffract light at three distinct wavelengths corresponding to red, green, and blue spectra, where the PBP lens includes a multilayer structure with alternating chiral and achiral liquid crystal layers, and the PBP lens has a transparency of at least 85% to wavelengths outside the red, green, and blue spectra.
What exactly they claim (claim 1)
1. An optical system comprising: a Pancharatnam-Berry Phase (PBP) lens configured to diffract light at three distinct wavelengths corresponding to red, green, and blue bands, wherein the PBP lens includes a multilayer structure with alternating chiral and achiral liquid crystal layers, and the PBP lens has a transparency of at least 85% to wavelengths outside the red, green, and blue bands.
