The azimuthally varying surface-relief profile advances the phase around the optical axis by 2πm per revolution; this unit has a topological charge of m = 1, so a single 2π helical ramp produces one unit of OAM and a central phase singularity (dark core) on axis. It is a single-piece Ø25.4 x 3 mm ultraviolet fused silica (UVFS) chip supplied bare, without a mechanical housing.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOptical vortex \/ OAM beam generation for structured light\u003c\/li\u003e\n  \u003cli\u003eOptical tweezers and micro-particle manipulation\u003c\/li\u003e\n  \u003cli\u003eStimulated-emission-depletion (STED) and high-resolution microscopy\u003c\/li\u003e\n  \u003cli\u003eOptical communication and information processing with OAM multiplexing\u003c\/li\u003e\n  \u003cli\u003eSurface topography measurement and beam-shaping research\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n\u003cp\u003eThe element is fabricated from ultraviolet fused silica (UVFS) by surface-relief micro-structuring, forming a continuous spiral staircase whose height increases along the azimuthal direction. UVFS offers low absorption and a high damage threshold, making it well suited to ultraviolet operation where polymer vortex retarders are unsuitable.

Note that the device is unmounted (bare chip), so use an appropriate holder that does not stress the surface and observe the beam-input orientation of the spiral structure. Store in the original container in a clean, dry environment away from direct sunlight, condensation and corrosive vapors.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":48755325010074,"sku":"VRF1-355","price":6146.52,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/quartz-vortex-wave-plate-vrf1-355.png?v=1784260594"}],"url":"https:\/\/waveqvanta.com\/collections\/lbtek-micro-nano-optics-vortex-retarders-quartz-vortex-wave-plate.oembed","provider":"WaveQuanta","version":"1.0","type":"link"}
