IS1.5-VIS-FPD-800
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.

FAQ
I need to measure the power of a diverging beam whose divergence is very asymmetrical; the Fast axis divergence is ± 80 degrees, while the Slow axis divergence is ± 20 degrees. Will the IS6-D integrating sphere work? It’s specified Maximum Beam Divergence is ± 60 degrees.
Simple Measurement.viProgram for those who want to use Centauri connected to IS1.5-VIS-FPD-800 or IS1.5-IRG-FPD-800 integrating spheres with LabVIEW 2017.
Note: In order to work with the application example, it is necessary to install the LabVIEW runtime engine 2017, downloadable from the National Instruments website.

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.
