The SP-50 Calibrated Spectral Flux Measurement Systems are composed of an SP-50 Diode Array Spectrometer, calibrated Integrating Sphere and Spectral Suite Software. SP-50 systems provide users with a simple to operate integrating sphere system that measures the amount of light entering the port of the integrating sphere.
The SP-50 Systems offer high sensitivity, low noise, and fine optical resolution. This combination of optimized performance characteristics makes the SP-50 series spectrometers perfect for calibrated spectral radiant flux measurement. The SP-50 spectrometers are design specifically for LED measurement, lamp measurement, and lighting measurement applications.
All spheres are calibrated to measure the total flux entering the port on the front of the integrating sphere. Integrating sphere sizes include diameters of 2, 6 and 12 inches.
