Product Details Supplier Info More products

Laser Components is able to supply vortex lens diffractive optics manufactured by Holo-Or for applications such as solar coronagraphs, high-resolution microscopy, optical tweezers, lithography and quantum optics.

The vortex lens optics convert a Gaussian beam into a doughnut-shaped energy ring.

Each vortex lens is wavelength specific.

Key information

  • The vortex lenses require a collimated single-mode Gaussian input beam, which is converted into a TEM01 axially symmetrical mode.
  • A spatial filter is used to increase the beam size — this reduces the sensitivity of the output to DOE alignment tolerances and will also result in the ability to produce a smaller vortex spot.
  • To achieve the best results, it is important to align the beam precisely in the plane of the nominal working distance.
  • It is also critical to ensure the use of high-quality beams, spatial filter and beam expanders.
