FocusGage – Stand Alone Tomographic Beam Profiler


focusGage – Stand Alone Tomographic Beam Profiler

Multi-axis knife edge scanning laser beam profiler extended to measurements of divergence and depth of focus

FocusGage™ is a versatile, multi-function PC based measurement system that provides the analytical and graphical power of the multiple-blades Beam Intensity Profiler, along with the ability to measure the 2 axis depth of focus, waist size, waist location, divergence (NA) of CW lasers and laser diodes. The depth of focus is measured by scanning the laser beam along its propagation axis and measuring beam size at different locations.

FocusGage™ has applications in laser printers, construction lasers, far-field alignment of lasers, particle measurement, fiber optics measurements and any application where the quality and shape of the beam effect system performance.
