Introduction
The spiral phase plate (SPP) is a new type of diffractive optical element that can produce a special light field with vortex. The vortex beam generated by an incident plane wave passing through the SPP is a special light field with phase singularity, a helical wavefront and a certain orbital angular momentum.
Custom Instructions
UPOLabs can provide customers with spiral phase plates of different wavelengths and sizes. The default is based on the quartz glass material, and the continuous surface type is designed and processed based on the Gaussian mode.
1. Default quartz rock material, please contact us if you have special material requirements.
2. Standard products can be supplied from stock within 6-8 weeks.
3. Topology load number is optional
