LBTEK Quartz Polarization Gratings are fabricated on UVFS substrates, featuring internally inscribed birefringent microstructures. They are presented as 1-inch single-substrate bare dies without housings. Within the substrate, the orientation of the fast axis of the birefringent microstructure varies periodically and continuously along the x-direction, while maintaining a uniform λ/2 retardation across the entire device plane, making it a single-wavelength device. Quartz polarization gratings exhibit polarization-dependent optical characteristics. Depending on the polarization state of the incident beam, they can be used to achieve a two-beam splitting effect with adjustable energy ratios or to enable non-mechanical beam scanning. Compared to traditional gratings, quartz polarization gratings introduce polarization modulation functionality; their planar structure, free of physical protrusions or depressions, facilitates integration; and the choice of substrate material ensures a high damage threshold in the ultraviolet band. LBTEK offers standard quartz polarization gratings with a working wavelength λ of 355 nm and a grating period p of 200 μm. We also support flexible customization of parameters and specifications to meet diverse application needs. For details, please contact LBTEK Technical Support.
