Focal Spot Analyzer
Measure your laser beam power distribution and focal spot size of wavelengths from 300 – 1100nm. The average power can be from <1 to 400 Watts and up to 5 kW for FSA-HP, the focal spot can be as small as 34.5μm. The FSA can also be used to measure how the focal spot shifts with power during its critical start-up phase.
