Photon Inc., San Jose, CA, has released a new adapter for the LD8900 and LD8900R goniometric radiometer far-field profilers that extends the real-time measurement capability for fibers, fiber delivery systems and other divergent sources to power levels up to the kilowatt range.

The adapter uses a UV-grade fused silica prism to sample the beam by front-surface reflection. It is available with most standard fiber connectors and is easily adaptable for direct interfacing of laser diodes as well.


In tests performed in a customer's laboratory, a model LD-8900 demonstrated the ability to measure a 532 nm beam of more than 700 W. Photon’s patented goniometric radiometers generate real-time far-field profiles and angular measurements of divergent sources, including full 3D analysis.
