Reimaging UV Laser Beam Profiling Ophir Photonics

Webradius is) is the most important propagation-related attribute of a laser beam. In case of a perfect top-hat (or flat-top) profile the beam diameter is clear but most laser beams have other transverse shapes or profiles (for example, Gaussian) in which case the definition and measurement of the beam diameter is not trivial. WebGTH beam shapers have a free-form surface which redistributes a Gaussian beam (TEM 00) into a rectangular Top Hat.Combination with nearly every focusing optic is possible. … WebFBS2 beam shapers generate small and homogeneous square Top Hat spots in the focal plane. Each FBS2 is made for a fixed input beam diameter with a ±5% tolerance. Lenses for wavelengths and beam diameters other than standard can be produced on request.
