{"product_id":"spiral-phase-plates-vp1-1064","title":"Spiral Phase Plates VP1-1064","description":"\u003cp\u003eThe LBTEK Spiral Phase Plate is a diffractive optical element that achieves phase modulation of light beams by varying the material height along the azimuthal direction, thereby generating vortex beams. When an incident plane wave passes through the spiral phase plate, it produces a vortex beam with a helical phase front, causing mutual cancellation at the optical axis and forming a central dark ring.\u003c\/p\u003e\n\n\u003cp\u003eSpiral phase plates offer advantages such as high efficiency, stability, ease of operation, and a high damage threshold, making them widely applicable in optical tweezers, high-resolution microscopy, information processing, and surface topography measurement. Compared to liquid crystal polymers, UV-grade fused silica features lower absorption, making it more compatible with ultraviolet applications.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUV fused silica material, spiral staircase structure\u003c\/li\u003e\n\u003cli\u003eApplicable for generating vortex beams with spiral phase wavefronts\u003c\/li\u003e\n\u003cli\u003eHighly efficient and stable, easy to operate, high damage threshold\u003c\/li\u003e\n\u003cli\u003eWorking wavelength: 355 nm, 532 nm, and 1064 nm; order m: 1, 2\u003c\/li\u003e\n\u003cli\u003eFlexible customization of parameter specifications available\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpiral Phase Plate Series\u003c\/h3\u003e\n\u003cp\u003eThe LBTEK spiral phase plate is fabricated from UV-grade fused silica using surface relief technology, featuring a spiral staircase structure.
