HOLO/OR Product Release

Cost effective vortex generator for microscopy laser applications by HOLO/OR Ltd.

Ness Ziona, Israel, November 2021

HOLO/OR, the world leader in high-power Diffractive Optical Elements (DOE) manufacturing, is proud to present its newly available family of affordable reduced cost microscopy vortex phase plate.

Vortex phase plates are often used in advanced microscopy, mostly in the STED and laser tweezing applications. By adding a vortex phase plate, it is possible to shape the spot to a donut-like distribution, with a central hole that is smaller than the diffraction limit. This enables sub-diffraction limit optical resolution by depleting fluorescent excitation in all areas outside the hole (as is done in STED), or trapping and manipulating very small particles, as is done in tweezing.

How do our vortex beam generators work? simple- a vortex phase plate is a flat optical element with a precise, micron scale depth helical structure on the active surface. This unique structure adds an orbital angular momentum to the beam propagated through it, that “pushes” the energy from the beam center, creating a donut like illumination profile.  Unlike liquid crystal-based vortex phase plates, that manipulate the spin momentum, our elements are not sensitive to polarization of the incoming light thus do not require any specific rotation angle vs the incoming beam.

HOLO/OR’s new microscopy vortex phase plates offer unparallel phase profile accuracy, providing precise shaping to a symmetrical donut, with no undefined area in the center of the plate. Our new vortex generators have a high LDT, suitable for illumination with > 1000 mW of laser power, are stable at typical microscope operating conditions (-40 to +120 ⁰C) and can be easily integrated into existing setups due to their small form factor. For interested customers, HOLO/OR can mount them in 1’’ holder frames to facilitate integration into the laser light path.

HOLO/OR has recently developed a new production process which enables us to offer these elements at affordable and competitive costs to meet the growing market’s needs.
