Optical power measurement
WebMeasuring optical power accurately requires capturing a known fraction of the emitted energy from the source. Inconsistent radiation collection or inaccurate measurements can cause an acceptable device to be graded incorrectly or rejected, reducing the manufacturing yield. This white paper offers an overview WebOptical Power Sensors Keysight optical power sensors are the right choice for accurate power measurements on fiber optic devices. The modular sensors fit into all Keysight 816x Lightwave mainframes and can be used singly or in multiples for parallel measurements of multichannel devices.
