Загрузить техническое описание

The 81628B optical power head has a built-in integrating sphere with wavelength-dependent calibration for accurate high power measurements. Distributing the power over a large surface away from the detector assures linearity and temperature stability. Functionality includes averaging time settings from 100 µs to 10 s, automatic power ranging, monitoring of minimum and maximum values and logging up to 20k samples. Fiber adapters are available for common connector types. including bare fiber clamps. (see www.Keysight.com/find/octaccessories)

The 81628B is used with the threaded type adapters. When the adapter is removed, the 8 mm diameter aperture is available for input to open beams or customized fiber holders. The heads are connected to the 816x mainframes using the 81618A single channel or 81619A dual-channel interface module.

Benefits

  • This measurement setup ensures the distribution of the high power equally to all parts of the sphere avoiding partial hot spots, which guarantess long lifetime and uncompromised reliability
