The device exhibits a uniform λ\/2 retardation across the entire plane, making it a single-wavelength component.\u003c\/p\u003e\n\n\u003cp\u003eThe vortex retarder possesses polarization-dependent optical characteristics. With different polarization states of the incident beam, it can generate vector-polarized beams or vortex beams with spiral phase fronts, converting TEM00-mode Gaussian beams into hollow \"doughnut-shaped\" intensity distributions.\u003c\/p\u003e\n\n\u003cp\u003eCompared to traditional methods of optical field modulation, the vortex retarder offers 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.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLiquid Crystal Polymer\/N-BK7 window plate, sandwich flat structure, with mechanical housing\u003c\/li\u003e\n\u003cli\u003ePolarization-dependent, applicable for generating vector polarized beams and vortex beams\u003c\/li\u003e\n\u003cli\u003eHighly efficient and stable, easy to operate, specialized function, large incident angle\u003c\/li\u003e\n\u003cli\u003eOperating wavelength λ: 405–1550 nm, order m: 1–128\u003c\/li\u003e\n\u003cli\u003eFlexible customization of parameter specifications available\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003em=2 Series\u003c\/h3\u003e\n\u003cp\u003eThe m=2 vortex waveplate is suitable for incident light with diameters ranging from Ø1 mm to Ø21.5 mm, with a conversion efficiency of ≥99.5%.
