Product Introduction

Vortex lenses convert a Gaussian input laser beam into a donut-shaped energy ring. A Vortex lens is a unique optic, whose structure is composed of spiral or helical phase steps. A Spiral phase plate converts a Gaussian input profile into a donut-shaped energy ring. The spiral phase plate is a unique optic, whose structure is composed entirely of spiral or helical phase steps, whose purpose is to control the phase of the transmitted beam.

The topological charge, denoted in the literature as m, refers to the number of 2π cycles (i.e. "staircases") etched around 360° turn of diffractive surface. One main effect of a higher topological charge is an increase in the angular momentum of the vortex beam by a factor of m. Another effect is the dimensions magnification of the ring intensity pattern, by a factor of m.
