Light source characterization goniometer system Photon Inc

LD 8900 Goniometric Radiometer
For Characterizing Laser Diodes, LEDs, VCSELs and Fiber Optics.

Photon's LD 8900 Goniometric Radiometer for characterizing the angular radiation intensity of light provides direct real-time far-field measurements with 24 dB dynamic range, angular sampling of 0.055° and a field-of-view of &plusmin;72° (144°). The LD 8900 is ideal for characterizing the light flux from many light-emitting sources, including VCSELs, laser diodes, optical fibers, optical wave-guides, and more. The LD 8900 provides full three-dimensional measures of the far-field pattern in minutes or less, with better resolution than a CCD camera.
The LD 8900 is available with either a silicon detector or an InGaAs detector, and has a standard entrance aperture of 2 mm, with an optional 10-mm entrance aperture for use with large sources such as LEDs and LD bars. The LD 8900 is a modular unit designed for R&D, manufacturing, and custom applications, such as testing LDs at the wafer level, measuring optical fiber attributes. The complete system includes:

The Scan Unit
The Motion Control Module
PC (monitor is user supplied) with the Goniometric Radiometer Model GS880 Scan Control and Data Acquisition Card installed
Goniometric Radiometer Acquisition and Analysis Software for user-specified MS Windows 98 or Windows NT 4.0
Power and Instrument Cables
An optional LD 8900 semi-custom source mount, specifically designed to meet your application needs, can be quoted upon request.
