HOLO/OR Polymer on Glass Vortex Phase Plates are a diffractive optical element (DOE) that converts Gaussian input beam profiles to donut-shaped energy rings. These plates convert collimated single mode TEM00 Gaussian input beams to TEM01 radially symmetric mode beams. The optical elements are composed of spiral-phase steps in a pattern which controls the phase of the transmitted beam. HOLO/OR Polymer on Glass Vortex Phase Plates feature an m=1 topological charge, and are designed for lower energy 488, 515, and 532nm applications such as STED Microscopy, academic research, and fluorescent excitation. For applications requiring higher power, HOLO/OR Diffractive Vortex Phase Plates are also available.
Note: Diffractive optical elements are not intended for use outside of their design wavelength. Diffractive optical elements will have decreased performance if their surfaces become dirty from oil or other substances. It is recommended to always use gloves or finger cots when handling these optics.
