Vortex Retarder Arrays VRIA-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 with SM1-8A mechanical housing
• m=1-9 vortex retarders in 3×3 integrated monolithic array
• Polarization-dependent; generates l=±1-9 vortex beam arrays
• Highly compact 1-inch substrate design
• Operating wavelength λ: 633 nm; orders m: 1-9

Integrated Type VRIA-633

Monolithic 1-inch substrate with 15 mm×15 mm clear aperture. Each sub-unit measures 5×5 mm, supporting beam diameters Ø0.3 to Ø3.2 mm. Engraved markers distinguish m-order positions. Capable of generating Laguerre-Gaussian beams with l=±1-9.
