ARCoptix - Variable Spiral Plate (VSP) for Vortex Beam Generation - Brochure

The variable spiral plate (VSP) is a passive liquid crystal optical element that is capable to modify a simple laser beam into a vortex beam, radial polarized beam having orital momentum (L=1 or L=2). The VSP is a perfectly transparent optical element without scattering or diffracted ligh losses (apart from the absorption losses of the material). The conversion from homogenous linear polarized beam to, for example, radial, azimuthal (or also lemon, spiral or star distribution) can simply be obtained by placing the VSP in the optical path of your laser beam.
