Wide Beam Imager
The Ophir Wide Beam Imager accessory provides a way to measure both
size and power distribution of a divergence and large diameter beam coming
from sources such as LED, VCSEL as well as large diameter parallel beams.
It employs a diffusive plate onto which the beam from the light source
impinges. The diffuser has a 45mm diameter clear aperture onto which the
laser beam or light source is projected.
This image is then reduced 8X and is reimaged onto the camera focal plane.
The accessory can be provided as a complete solution that includes
BeamGage Professional imaging and analysis software, and high-resolution
The product provides a solution for the measurement of divergence or
large beams with moderate spatial resolution.
BeamGage is giving me results that are very different than expected.
Can it measure smaller diameters than specified 10mm?
What is the maximum power?
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
