积分球

Keysight 是德科技 Agilent 81002FF 积分球
81002FF积分球 - 球有一个外径80毫米，并具有高度扩散内衬材料。的一个基本思想是光线进入的领域，是散布在室内表面均匀功率密度。在总功率小部分退出该领域，通过一个小的光圈在光学头检测器。球体是用于多种应用程序： 

高功率 - 创建了一个球约41 dB的衰减，具有zui大功率40 dBm的规范+（10瓦），提供zui高的功率处理能力可用。球的大小允许这个高功率是很容易扩散和消散。注：球可以建一个稍微大口径的光学头，减少到大约31 dB的衰减。较大的光圈，这是特殊的选项可用＃500。 

大光束直径/大数值孔径 - 球体的大尺寸，使一个很大的光功率“目标”，允许它从一个测量点源不适用了0.5和9毫米到一个开放的光束。该发射装置或光纤到球体对齐非关键
 
The Agilent 81002 FF Integrating Sphere is an accessory for the
Agilent 8163A Lightwave Multimeter, Agilent 8163A Lightwave
Measurement System, Agilent 8166A Lightwave Multichannel System,
and the HP 8153A Lightwave Multimeter. It can be used with all Agilent
Technology Optical Heads and all HP Optical Heads.
The Integrating Sphere is compatible with all connector adapters and
bare fiber adapters Agilent 81000xx, which can be used with these
optical heads.
 
Connections to the Agilent 81002 FF Integrating Sphere
The Agilent 81002 FF Integrating Sphere has three main advantages, it
allows measurements with:
• high optical power levels,
• large emission sources, either widely diverging point sources (high
numerical aperture (NA)) or light sources with large beam diameters,
• polarized optical sources; it scrambles the input polarization.
The Agilent 81002 FF Integrating Sphere allows the measurement of high
optical power levels up to 10 W (+40 dBm) due to its typical optical
attenuation of 40 dB. The optical loss of the integrating sphere shifts the
dynamic range of a connected optical head by +40 dB to higher power
