High Speed, Multifunctional Integrating Spheres

The IS1.5-VIS-FPD-800 contains 2 photodiodes: a calibrated photodiode for precise power measurement using Ophir meters and a fast photodiode with integral reverse bias circuit for temporal characterization using third-party instrumentation such as oscilloscopes and spectrum analyzers. Its small, 1.5" internal diameter preserves the temporal shape of pulses down to 3.5 nsec. An SMA fiber optic connector is provided for connection to a spectrometer. The large, 20 mm input aperture allows for wide acceptance angles and long working distances, making the IS1.5-VIS-FPD-800 well suited for testing VCSELs and other types of laser diodes in the spectral range of 400 nm to 1100 nm with average power output up to 4W.
