Ring Generator

HOLO/OR is a high-tech company dedicated to the design and manufacturing of ring generator DOEs.
A Ring generator transforms a laser beam into a ring (by a Diffractive axicon DOE for MM lasers and by a Vortex DOE for SM lasers) or into a multiple amount of rings (by a Multi-Circles DOE).
The Spiral Phase Plate (Vortex) transforms a Gaussian Single Mode TEM00 laser to a very small ring according to the topological charge. See our application notes on the Spiral Phase Plate for more information on the topological charge.
A diffractive axicon transforms any input beam to a small or large ring and also images a point source into a line along the optical axis and increases the DOF (Depth Of Focus).
A Multi-Circle DOE was recently proved to be the most appropriate light pattern for certain 3D mapping applications, especially with pipe/tube objects.

Spiral Phase Plate (Vortex)
Vortex DOE - ring donut shape - Holo/Or
A Spiral Phase Plate (Vortex) DOE converts a Gaussian input laser beam into a small donut-shaped energy ring. The topological charge of the Spiral Phase Plate (Vortex) will determine the ring diameter.
