LED Profiler - Generates high dynamic range light intensity profiles of LEDs. The LED 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 packaged or bare chip LED inserted directly into the center of the instrument's radial measurement area. The goniometer makes a ±130 degree measurement around the source, with 0.05 degree resolution. For the third measurement the mounting chuck is automatically rotated around the phi angle. This measurement can comprise from 10 to 200 cuts or 18 to 0.9 degrees per cut. The values reported are: Angular width of the light beam Spatial Profile of device. Power in the Cone
