How do I input correct magnification of WB-I VIS
What are recommended measurement parameters for WB-I VIS ?
According to the light source and beam geometry, customer will choose the measurement parameters which will yield most suitable results for the application, e.g. D4σ is the best for gaussian fit at M2 = 1, 50% of Peak value (FWHM) for "Tophat". For repeatable and reproducible results, use the UltraCal and Aperture features. For divergence angle measurements, distance from source to imaging screen should be measured. Screen is 0.5mm inside support tube end surface. The Divergence Angle measurements can be enabled in the Results area of the BeamGage application: In BeamGage, go to "Computation" > Divergence >Far Field Wide Angle settings to set distance from source to WB-I VIS screen.Close
BeamGage shows results that are very different than expected.
Can it measure smaller diameters than specified 10mm?
What is the maximum power?
The Ophir WB-I SWIR is a Wide Beam Imager accessory designated for SWIR 900-1700nm, especially popular 1550nm wavelength.
It's a compact system for measuring the size and power distribution of large and divergent beams of VCSELs, LEDs and large lasers.
Enables analyzing beams that are too large or divergent for a standard beam profiler
The Ophir Wide Beam Imager accessory is a compact, calibrated optical system for measuring the size and power distribution of large and divergent beams of VCSELs, LEDs, edge emitting
lasers, and fiber lasers. It lets you analyze beams that are too large or too divergent for a conventional beam profiler alone

VCSEL Near-Field Profiling and Testing in Production
The LBS-400 beam sampler attachment for Pyrocams and large format Beam Profilers allows measuring UV, NIR or IR wavelength laser beams with diameters up to 1 inch (25.4mm) and powers ranging from 10mW to ~500W(1). The output beam preserves the polarization of the original beam.
