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=64 Series\u003c\/h3\u003e\n\u003cp\u003eThe LC molecules' fast axis orientation of the LBTEK m=64 vortex waveplate rotates 180°×64 within a 360° central angle along the substrate's azimuthal direction, with its morphology under linearly polarized light shown in the figure. The m=64 vortex waveplate is suitable for incident light with diameters ranging from Ø3 mm to Ø12 mm. When illuminated with circularly polarized light, it can generate Laguerre-Gaussian beams with l=±64; 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. On the standard SM1 lens tube housing, the product name and model are labeled, with four engraved lines marking the center point.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eApplicable to incident light with dimensions Ø3 to Ø12 mm\u003c\/li\u003e\n\u003cli\u003eCapable of generating Laguerre-Gaussian beams with l=±64\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":47481771098266,"sku":"VR64-633","price":1040.18,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/8444f971ba212b98a8d6e8c9cdd17519_c0a3e655-81b8-4be2-a028-94bb5b9653bc.jpg?v=1771995881","url":"https:\/\/waveqvanta.com\/products\/polymer-vortex-retarders-vr64-633","provider":"WaveQuanta","version":"1.0","type":"link"}
