The SP-75 spectrometer /spectroradiometer offers the highest sensitivity, low noise, and fine optical resolution. The SP-75’s sensitivity makes it ideally suited for high-speed, triggered single pulse or PWM calibrated spectral irradiance measurements, or radiant flux measurements when combined with an integrating sphere and calibrated (this combination is offered as our LMS-SP75-X light measurement system).
