The Ophir IS1.5-VIS-FPD-800 is a 1.5” high speed response, multi-functional integrating sphere designed to provide multiple measurement capabilities in a single device. This includes the capabilities of a precision photodiode for calibrated average power measurement, a fast photodiode for pulse shape characterization on an oscilloscope and a built in SMA fiber adapter, and an SMA fiber optic adapter for easy connection to a spectrometer.
The IS1.5-VIS-FPD-800 features 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 0.7 ns. Together with its fast silicon photodiode, the IS1.5-VIS-FPD-800 provides a pulse rise time of 0.8 ns and a fall time of 2.8 ns.
