LD 8900 and LD 8900R Goniometric Radiometers

Profiling divergent light sources present many challenges, but Photon's patented Goniometric Radiometer Far-Field Profilers characterize the angular radiation intensity of light sources, such as laser diodes, LEDs, optical fiber, and waveguides simply and accurately without moving either the source or the detector. The LD 8900 and LD 8900R (higher dynamic range) Goniometric Radiometers are available with either a silicon or InGaAs detector and provide direct real-time far-field measurements of the far-field pattern in minutes or less.

The LD 8900HDR Far-Field Profiler uses goniometric methodology to measure true 3- dimensional profiles of optical components with up to 93 dB dynamic range. The LED Profiler characterizes and analyzes the output of light emitting diodes (LEDs).

“After finishing the evaluation of available far-field measurement systems we have decided to use the LD8900 for our future developments. That's because of its performance and its easy integration from the software and hardware aspect. We also appreciate the fast and competent support from Photon during the system optimisation.”
