Converting a Gaussian beam into an optical vortex beam, the Spiral Phase Plate SPP-1064-2-S11-C is also known as a vortex phase plate or a vortex lens.The spiral phase plate (SPP) is a phase-type diffractive optical element (DOE) whose optical thickness is proportional to the rotation of the azimuth angle.
A special light field including a spiral phase structure and orbital angular momentum (OAM), Vortex beam has been widely used in many fieldssuch as optical communications, optical tweezers, quantum information transmission, Solar coronagraphs and the super -resolution imaging.
Standard wavelength is 532nm, 632.8nm, 808nm, 1064nm, and 1550nm. Other wavelengths, component sizes and topological charges of SPPs are also available. Same of them are available in stock.
