IS1.5-VIS-FPD-800 7Z02491 Precision Photodiode Description：

The IS1.5-VIS-FPD-800 provides multiple measurement capabilities in a single integrating sphere device: a) a precision photodiode for calibrated average power measurement, b) a fast photodiode for pulse shape characterization on an oscilloscope and c) an SMA fiber optic adapter for easy connection to a spectrometer. The IS1.5-VIS-FPD-800 has a small internal diameter of 1.5 inch (38mm), to minimize the pulse stretching effect inherent to integrating spheres, giving it a time constant of 0.7ns. Together with its fast silicon photodiode, the IS1.5-VIS-FPD-800 provides a pulse rise time of 0.8ns and a fall time of 2.8ns.
