{"product_id":"vr1-488","title":"VR1-488 True Zero Order Polymer Vortex Half Wave Retarder 488nm","description":"\u003cp\u003eThe Vortex Retarder (VR) is fabricated with an N?BK7 glass substrate and Liquid Crystal Polymers (LCP). It features a sandwich structure consisting of front?and?rear glass substrates with a functional LCP film layer in?between, and is housed in a standard SM1 lens tube.\u003c\/p\u003e\u003cp\u003eWithin the LCP layer, the fast?axis orientation of liquid?crystal molecules is radially uniform across the substrate and varies continuously in the azimuthal direction.\u003c\/p\u003e\u003cp\u003eThis device delivers a uniform ¦Ë\/2 retardance across the entire aperture and is designed for single?wavelength operation.\u003c\/p\u003e\u003cp\u003eThe vortex retarder exhibits polarization?dependent optical properties. Depending on the polarization state of the incident beam, it can generate vector?polarized beams or vortex beams with helical phase wavefronts. It converts TEM???mode Gaussian beams into a donut?shaped hollow intensity distribution (refer to technical notes for detailed optical performance).\u003c\/p\u003e\u003cp\u003eCompared with conventional light?field modulation methods, vortex retarders offer advantages including high efficiency, reliable stability, easy operation and dedicated functionality. Its true?zero?order characteristic also enables low wavelength sensitivity, superior temperature stability and a large acceptable incident?angle range.\u003c\/p\u003e\u003cp\u003esupplies standard vortex retarders with operating wavelengths ¦Ë ranging from 405?1550?nm and order m from 1?128. Flexible customization of specifications is also available to meet diverse user requirements for various application scenarios.
