PHOTON INC. is a leading supplier of Laser Beam Profilers and electro-optical instrument systems for fast and accurate measurement, testing and analysis of laser and light sources, optical components for telecommunications, and other applications.
PHOTON INC. manufactures Far Field Profilers that use goniometric radiometer technology to provide real-time measurements of divergent light sources. Based on a patented scanning method in which neither the source nor the detector moves, user obtains full 3D hemispheric irradiance measurements with greater resolution and speed than tradition goniometric techniques.

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 and angular sampling of 0.055°. 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.

Photon's LD 8900R Wide Dynamic Range Goniometric Radiometer characterizes the angular radiation intensity of light. The LD 8900R provides direct real-time far-field measurements with >36 dB dynamic range, angular sampling resolution of 0.055° and a field-of-view of ±72° (144°). The LD 8900R is ideal for characterizing the light flux from many sources, including VCSELs, laser diodes, optical fibers, optical waveguides, and more.
The LD 8900R provides full three-dimensional measures of the far-field pattern in minutes or less, with far better resolution than a CCD camera. Measurement of the Mode-Field Diameter of optical fiber is now possible in real time with greater than 5% accuracy. Its dynamic range is wider, greater than 36dB, compared to the standard 24 dB.

HDR Far Field Profiler
Highest Dynamic Range; Fast, Accurate Measurements
The 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. All measurements are taken with the emitting fiber, planar waveguide, laser diode or LED inserted directly into the center of the instrument's radial measurement area. For optical fiber, the far-field distribution pattern is acquired without bending the fiber.
