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=4 Series\u003c\/h3\u003e\n\u003cp\u003eThe m=4 vortex waveplate is suitable for incident light with diameters ranging from Ø1 mm to Ø21.5 mm. When illuminated with circularly polarized light, it can generate Laguerre-Gaussian beams with l=±4; under linearly polarized light, it produces higher-order vector polarized beams. The smaller the selected order m, the smaller the central hole size of the beam.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eApplicable to incident light with dimensions Ø0.15 to Ø21.5 mm\u003c\/li\u003e\n\u003cli\u003eCapable of generating Laguerre-Gaussian beams with l=±4\u003c\/li\u003e\n\u003cli\u003eCapable of generating higher-order vector polarized beams\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47481766641818,"sku":"VR4-488","price":866.81,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/234ef766043635c4bfc5b2249a8af907_2dd8c1c4-2654-4da4-bfc4-d1b8a22d2b6b.jpg?v=1771995770","url":"https:\/\/waveqvanta.com\/products\/polymer-vortex-retarders-vr4-488","provider":"WaveQuanta","version":"1.0","type":"link"}
