概览

The IS1.5-VIS-FPD-800 multifunctional integrating sphere provides multiple measurement capabilities in a single integrating sphere device ideal for LIV testing and other divergent sources (e.g. VCSEL) measurements. The sphere includes 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.

Fast photodiode for pulse shape characterization of divergent sources (e.g. VCSEL)
Internal diameter of 1.5 in. to minimize the pulse stretching effect
Pulse with as low as 3.5s
Built in SMA fiber adapter for connection to a spectrometer
20 mm input port enabling long working distance
Accepts beams with divergence angles up to ±60°

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.

常见问题

The damage thresholds for your Integrating Sphere sensors are only given for the sphere surface – what about for the detector?
回答
The damage threshold is given in the datasheet for the sphere inner surface rather than for the detector itself, because the sphere surface will reach its damage threshold long before the detector will. A beam entering the sphere will first hit the inner surface on the opposite side of the sphere, and if at that point the power density is too high it will damage the inner surface of the sphere. From that first "meeting" of the beam with the white diffuse reflective inner sphere surface, it will be diffusely reflected multiple times. Since there is no direct line of sight between the entrance port and the detector, any light reaching the detector has already been uniformly distributed around the inner surface of the sphere, but light in that "first impact" on the sphere wall has not yet been uniformly distributed. Therefore, the "damage threshold" for the device is the maximum power density of the beam as it first hits the inner wall.

I need to measure the power of a very asymmetrically diverging beam; 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.
回答
The IS6-D type integrating spheres (such as IS6-D-VIS, IS6-D-UV, IS6-D-IR) will be good for this as long as you orient the 80 degree divergence in the vertical direction. The IS1.5-VIS-FPD-800 will also work, with the same constraint.
