Focal Spot Analyzer
⠀⠀⠀⠀⠀⠀⠀⠀⠀

Measure your laser beam power distribution and focal spot size of wavelengths from 266 – 1100nm. The average power can be from <1 to 400 Watts and the focal spot can be as small as 37µm. The FSA can also be used to measure how the focal spot shifts with power during its critical start-up phase.
The FSA is a combination of a camera, Beam Splitter, neutral density filters and a BeamGage software.
