Each single-layer retarder features uniform radial alignment of the liquid crystal molecules' fast axis with a continuous azimuthal gradient, providing a λ\/2 retardation.\u003c\/p\u003e\n\n\u003cp\u003eThe three-layer design, stacked at designed angles, forms the overall fast axis orientation and λ\/2 retardation, enabling spatial light field modulation. The device can generate vector-polarized beams or vortex beams with spiral phase fronts, converting TEM00 Gaussian beams into hollow-core intensity distributions.\u003c\/p\u003e\n\n\u003cp\u003eCompared to single-wavelength retarders, the achromatic version is not limited to specific working wavelengths and is suitable for broadband light sources.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLiquid crystal polymer\/N-BK7 window material, 3-layer glass substrate + 3-layer LCP film, with mechanical housing\u003c\/li\u003e\n\u003cli\u003eThree-layer LCP films stacked to form an achromatic vortex retarder for broadband operation\u003c\/li\u003e\n\u003cli\u003eHigh efficiency and stability, broad spectrum applicability, large incident angle\u003c\/li\u003e\n\u003cli\u003eOperating wavelength: 400-700 nm, 600-800 nm, 700-1100 nm; order m=1\u003c\/li\u003e\n\u003cli\u003eFlexible customization of parameter specifications available\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003em=1 Achromatic Vortex Waveplate\u003c\/h3\u003e\n\u003cp\u003eApplicable to incident light with diameters Ø0.5 to Ø21.5 mm.
