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 a built in SMA fiber adapter, 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.

Product Overview: Multifunction Integrating Sphere IS1.5-VIS-FPD-800 Product Overview: Multifunction Integrating Sphere IS1.5-VIS-FPD-800

In many applications such as VCSEL-based LIDAR and facial recognition systems, there is a need to measure multiple parameters of the laser beam at the same time, such as power, spectrum, and temporal pulse shape. Also, capturing and correctly measuring these widely-diverging and slowly-pulsing beams can be very challenging.
The Ophir IS1.5-VIS-FPD-800 Multifunction Integrating Sphere sensor helps you meet these challenges. Get an overview in this video.
