Photon has introduced its new high-power adapter for the LD8900 and LD8900R goniometric radiometer far-field profilers, which extends the real-time measurement capability for fibres, fibre delivery systems and other divergent sources to power levels in 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 fibre connectors and is easily adaptable for direct interfacing of laser diodes as well. In tests performed in a customer laboratory, a model LD-8900 demonstrated ability to measure a 532nm beam of more than 700 Watts. Photon’s patented goniometric radiometers generate real-time far-field profiles and angular measurements of divergent sources, including full 3D analysis.
