LD8900 & LD8900R Beam Profiling Systems for Divergent Light Sources

Profiling divergent light sources presents many challenges, but Photon's far-field profilers characterize the angular radiation intensity of light simply and accurately in real time. Both the LD 8900 and LD 8900R (wide dynamic range Goniometric Radiometer) provide full 3-dimensional measurements of the far-field pattern in minutes or less, with far better resolution than a CCD camera.

    FAQ

    I have just reloaded my LD8900 software onto a new computer and now the system doesn't work. It says that the signal is saturated, even when there is no light input.

    There are two different models of the LD8900 Goniometric Radiometer (far-field profiler), the LD8900 and LD8900R. The former is an 8-bit system and the latter a 16-bit and they have different controller cards and software. If you have both systems in your facility be sure that you are loading the correct software type for the instrument you are trying to operate. Mixing either the software or the controller PCBs for these will result in this non-performance symptom. Make sure that you get the correct software for your system—16-bit LD8900R for the LD8900R or 8-bit LD8900 for the LD8900.

    • Pulsed InGaAs Option

      PH00185

      Failsafe operation for pulsed sources operating at repetition rates >10kHz with pulse widths >500ns. For operation below 10kHz, there are possible gain saturation states, dependent on repetition rate, pulse width, and source power. Consult the factory when operating under these conditions for failure mode assessment. When questionable, pulsed source operation should be verified against CW operation.

    • Pulsed InGaAs Upgrade Option

      PH00186

      Pulsed Upgrade Option to an existing Goniometric Radiometer InGaAs system. Failsafe operation for pulsed sources operating at repetition rates >10kHz with pulse widths >500ns. For operation below 10kHz, there are possible gain saturation states, dependent on repetition rate, pulse width, and source power. Consult the factory when operating under these conditions for failure mode assessment. When questionable, pulse source operation should be verified against CW operation. Includes software upgrade. Contact Factory for details.
