- Page 2 USER NOTES PART # 8J06009. REV 01 DIMENSIONS FSA-HP with SP932U Camera INTRODUCTION The Focal Spot Analyzer for High Power lasers allows measuring NIR (~1064nm) focused or collimated laser beams profiles up to 5kW or 15MW/cm and calculating the focal spot position with 50 µm accuracy. A fraction of the incoming beam is reflected through the front surfaces of a pair of orthogonally oriented wedges.

REV 01 Incident Reflection: Less Laser Beam Reflection: Less than than 0.1 % of the 0.0001 % of the beam beam directed directed towards Ophir towards Ophir Beam Profiler Camera power meter 99.9 % of the beam passes through Each direction provides uniform attenuation of any beam shape: gaussian, flat-top, doughnut shape while...

Page 4: Factory Calibration
USER NOTES PART # 8J06009. REV 01 FACTORY CALIBRATION Focal Spot Analyzer is pre-calibrated in the factory with 50µm accuracy between the top surface (datum) and the camera sensor. A detailed explanation about optical path length measurement is provided in section Optical path calculation The camera orientation can be easily rotated to fit the needs of your beam. - Page 5 USER NOTES PART # 8J06009. REV 01 OPTICAL PATH CALCULATION With the beam traveling through the ND filters, there is an inherent offset that occurs. This offset must be considered when determining the actual beam path distance. Each beam splitter housing and ND Filter holder has its own calibrated dimensions printed and placed on the unit.

USER NOTES PART # 8J06009. REV 01 INSTALLATION AND SETUP 1. The FSA contains of beam splitter attached to the camera as shown above. Camera can be rotated at any required orientation as descried in Factory Calibration. 2. Position the FSA so the laser beam enters the center of the input port at a 90° incidence. 3. -
Page 7: Operation
USER NOTES PART # 8J06009. REV 01 OPERATION 1. Start the beam profiler software and adjust the ND filter holders until the maximum beam intensity is approximately 80% of saturation. See Appendix A for ND filter details. If there are interference effects seen, slight angling of the setup to the beam path may eliminate this. 2. -
