LBTek Polarization Gratings (PG) are fabricated based on liquid crystal polymer birefringent materials and N-BK7 glass substrates, presenting a sandwich structure of front and rear glass substrates plus intermediate LCP functional film layer.
The fast-axis orientation of liquid crystal molecules exhibits a periodic continuous gradient along the x-direction, maintaining half-wave retardation across the entire device plane.
Key Features
- Liquid Crystal Polymer / N-BK7 window plate sandwich flat plate structure
- Half-wave retardation capability
- Energy proportion-adjustable beam splitting and beam scanning functions
- Flat plate structure, polarization-dependent, high diffraction efficiency
