Vortex Retarder Arrays VRA-633

The LBTEK Vortex Retarder Array combines N-BK7 glass substrate and Liquid Crystal Polymer (LCP) material into a 3×3 arrangement, generating vortex beam arrays with l=±1-9 or various vector polarization configurations.

Compared to single vortex retarder units, the array offers higher integration, making it more suitable for applications involving vortex beam arrays while maintaining advantages like high efficiency, stability, and broad incident angles. The zero-order design ensures low wavelength sensitivity and high temperature stability.

Key Features

• Liquid Crystal Polymer/N-BK7 window plate sandwich structure
• m=1-9 vortex retarders in 3×3 split array configuration
• Polarization-dependent; generates l=±1-9 vortex beam arrays
• High integration with high efficiency and stability
• Operating wavelength λ: 633 nm; orders m: 1-9

Split-Type VRA-633

Nine half-inch units mounted 15 mm apart center-to-center, with Ø10 mm clear aperture per sub-unit. Accommodates beam sizes Ø0.3 to Ø10.0 mm. Capable of generating Laguerre-Gaussian beams with l=±1-9 and various vector polarization beams.
