The LBTEK Vortex Retarder (VR) is fabricated using N-BK7 glass substrates and Liquid Crystal Polymer (LCP) materials, featuring a sandwich structure of "front and rear glass substrates with an intermediate LCP functional layer," and is mounted in a standard SM1 lens tube. In the LCP layer, the fast-axis orientation of the liquid crystal molecules is uniformly aligned along the radial direction of the substrate and continuously varies along the angular direction. The device exhibits a uniform λ/2 retardation across the entire plane, making it a single-wavelength component. The vortex retarder possesses polarization-dependent optical characteristics. With different polarization states of the incident beam, the vortex retarder can be used to generate vector-polarized beams or vortex beams with spiral phase fronts, converting TEM00-mode Gaussian beams into hollow "doughnut-shaped" intensity distributions (see detailed optical properties in the technical specifications). Compared to traditional methods of optical field modulation, the vortex retarder offers advantages such as high efficiency, stability, ease of operation, and dedicated functionality. Its true zero-order characteristic also contributes to low wavelength sensitivity, high temperature stability, and a wide range of incident angles. LBTEK provides standard vortex retarders with working wavelengths (λ) ranging from 405 to 1550 nm and orders (m) from 1 to 128, as well as flexible customization of parameters to meet diverse application requirements.

The m=1 vortex waveplate is suitable for incident light with diameters ranging from Ø1 mm to Ø21.5 mm, achieving a conversion efficiency of ≥99.5%. When illuminated with circularly polarized light, it can generate Laguerre-Gaussian beams with l=±1; under linearly polarized light, it produces vector polarization beams, including two special cases: radially polarized beams and azimuthally polarized beams. The smaller the selected vortex waveplate order m, the smaller the central hole size of the beam. On the standard SM1 lens tube housing of the vortex waveplate, the product name and model are labeled, and four engraved lines mark the center point of the vortex waveplate. Additionally, based on the fast axis sensitivity of the m=1 vortex waveplate, a single dot marks its 0° fast axis.
