NEWPORT   优铂特    819-IG-1.5-800PS   1.5英寸高速响应多功能积分球   Multifunctional Integrating Sphere, 2 Detectors, 1.5 in. ID, 600 nW to 3 W, Ø20 mm, 940 to 1640 nm       The 819-IG-1.5-800PS multifunctional integrating sphere provides multiple measurement capabilities in a single integrating sphere device: a) a precision InGaAs photodiode for calibrated 940-1640 nm average power measurement, b) a fast photodiode for pulse shape characterization on an oscilloscope and a built in SMA fiber adapter, and c) an SMA fiber optic adapter for easy connection to a spectrometer. The 819-IG-1.5-800PS has a small internal diameter of 1.5 inch (38 mm), 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,...
