Flat-plate Cylindrical Lenses PBCL25-633-F100

The LBTEK Flat-plate Cylindrical Lens is a diffractive optical element constructed on an N-BK7 glass substrate using liquid crystal polymer material, featuring a sandwich structure with front and rear glass substrates encasing an intermediate LCP functional layer.

The flat-plate cylindrical lens possesses polarization-dependent optical characteristics, enabling control over the energy distribution of converging and diverging light spots by manipulating the polarization state of the incident light. It functions as both converging and diverging lens through polarization control.

As a flat-structured diffractive device, the continuous variation of periodic structure provides spherical aberration-free properties. All rays passing through the effective aperture converge at the same position, forming a vertical focal line.
