    The Spiral phase plate converts a Gaussian beam into an optical vortex beam, It is also called Vortex phase plate. 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. 
    Vortex beam is a special light field including a spiral phase structure and orbital angular momentum (OAM), which has been widely used in many fields. Such as optical communications, optical tweezers, quantum information transmission, Solar coronagraphs and the super -resolution imaging. 
    The topological charge L is very important, it refers to the number of 2π cycles etched around 360° turn of SPP surface. One main effect of a higher topological charge is an increase in the angular momentum of the vortex beam by a factor of L. 
    We manufacture the Vortex phase plate (VPP) by moving mask technology. Using a 2D specific mask, the target optical surface can be completed by a single moving exposure process. Different types of SPPs were fabricated by using the method, whose roughness are less than tens nanometers.

    Spiral phase plate (SPP) Processing capacity
    Comparing to the traditional multiple overlay exposure method, our moving mask technology is easy to fabrication and more cost effective. We could manufacture the SPP with different wavelength, topological charge and element sizes. The delivery is usually 2~4 weeks (uncoated).
