Vortex Phase Plate
LETO series Vortex phase plate is based on fused Shi Ying glass substrate, continuous surface and semiconductor processing technology, which is an important device to generate vortex beam. A vortex phase plate (VPP) is a diffractive optical element, which can generate a special light field with vortex. It is widely used in many fields, such as binding tiny particles, quantum information transmission, light gradient force research and so on.
