For laser powers up to 400W and up to 5kW for FSA- HP version
Can measure systems with focal length as short as 73mm
Produces undistorted sample of laser under test
Adjustable attenuation maximizes system dynamic range
Up to 1 x 10-10 attenuation available
Analyzer includes camera, attenuation, BeamGage software and calibration certificate
The FSA is a combination of a camera, Beam Splitter, Neutral Density filters and a BeamGage software.

Focus analyzer drawing

FSA-HP For measurement of focal position and profile of high-power lasers above 1kW at NIR (~1064nm) region, FSA-HP version can be used. It allows same operation as standard FSA but operates up to 5kW or 15MW/cm2 without significant heating. Only 0.0001% (1/106) of the incident beam is reflected towards Ophir Beam Profiler, enabling beam sampling of extremely high powers and power densities.
