m=1-9 vortex retarders arranged in a split or integrated 3×3 array
Polarization-dependent, applicable to generate l=±1-9 vortex beam arrays, capable of producing various vector polarization beam arrays
High integration, high efficiency and stability, easy operation, large incident angle
Operating wavelength λ: 633 nm, order m: 1-9
Flexible customization of parameter specifications available

The LBTEK Vortex Retarder Array (VRA) is fabricated using N-BK7 glass substrate and Liquid Crystal Polymers (LCP) material, combining vortex retarder units with m=1-9 into a 3×3 array in either discrete or integrated form, mounted in standard SM1 lens tubes or customized mechanical fixtures. With different polarization states of the incident beam, it can be used to generate vortex beam arrays with l=±1-9 or various vector polarization beam arrays. Compared to single vortex retarder, the vortex retarder array offers higher integration, making it more suitable for applications involving vortex beam arrays, while retaining the advantages of flat optical components such as high efficiency, stability, and ease of operation. Its true zero-order characteristic also contributes to low wavelength sensitivity, high temperature stability, and a wide range of incident angles. LBTEK provides vortex retarder arrays with a working wavelength λ of 633 nm and orders m=1-9 in both discrete and integrated configurations, and supports flexible customization of parameters to meet diverse application requirements.

Split-type Vortex Waveplate Arrays, m=1-9

Capable of Generating Laguerre-Gaussian Beams with l=±1-9
Capable of Generating Various Vector Polarization Beams
Applicable to beam sizes ranging from Ø0.3 mm to Ø10.0 mm

The LBTEK m=1-9 half-inch vortex waveplates are mounted in a specially designed fixture, arranged in a 3×3 square array. Following the left-to-right, top-to-bottom distribution sequence, the orders m of the vortex waveplates range from 1 to 9, with a center-to-center distance of 15 mm between adjacent vortex waveplate units. Each individual vortex waveplate has a clear aperture of Ø10 mm and is suitable for light beams ranging in size from Ø0.3 mm to Ø10.0 mm. It can be used to generate l=±1-9 Laguerre-Gaussian beam arrays or various vector polarization beam arrays.

Integrated Vortex Waveplate Arrays, m=1-9

Capable of generating Laguerre-Gaussian beams with l=±1-9
Capable to Produce Various Vector Polarization Beams
1-inch Substrate, 15 mm×15 mm Clear Aperture, Highly Compact Design
Suitable for Beam Diameters Ranging from Ø0.3 mm to Ø3.2 mm

The LBTEK m=1-9 integrated vortex waveplate array is capable of generating l=±1-9 Laguerre-Gaussian beams and various vector polarization beams. Its monolithic structure is integrated on a 1-inch substrate with a clear aperture of 15 mm × 15 mm, featuring highly compact characteristics. Each vortex waveplate sub-unit measures 5 mm × 5 mm and is suitable for incident beams ranging from Ø0.3 mm to Ø3.2 mm in diameter. On the 1-inch mechanical sleeve housing, markings are engraved to help customers distinguish the m-order arrangement of each unit in the array—the two positions marked with engraved lines + circular dots and engraved lines only correspond to the m=1 and m=9 vortex waveplate units, respectively. At the m=1 vortex waveplate unit, the direction from the engraved line to the circular dot indicates the increasing order of m values (1, 2, 3, etc.).
