A vortex lens, in literature also referred to as spiral phase plate, finds application in many cutting edge scientific and technological developments such as stimulated emission depletion (STED) microscopy, optical vortex chronographs, nano-lithography, ranging as well as optical trapping. In addition, vortex lenses play a considerable role in modern data transfer and data cryptography.
A vortex lens is an optical component that converts an initially Gaussian laser beam profile into a doughnut-shaped beam profile. The quality of a vortex lens is defined by the achieved intensity contrast between the dark center of the doughnut profile and the high-intensity outer ring.
We are excited to introduce an advanced vortex lens, which provides a unique doughnut beam quality that is achievable with a single, steady optical component.
Our vortex lens consists out of 64 precisely positioned steps, that build the spiral structure. This innovative, high-number step design is unique and responsible for the excellent quality of the doughnut-shaped beam profile. Fabricated in Germany, our vortex lens is made out of resistant fused silica to ensure an impeccable application in high-power pulsed laser systems.
Currently, we have vortex lenses for 532, 775 and 800 nm optical wavelengths on stock, and we are happy to customize our vortex lens to your individual wavelength and dimension purposes.
Our vortex lens possesses a single nanometer geometry accuracy and has two size options of 11 x 11 x 2.5 and 22 x 22 x 2.5 mm with a 10 and 20 mm working aperture. Due to its 1/2 or 1 inch rounded corners, the lens can be conveniently placed into a regular 1/2 or 1 inch holder or adapter.
