Optical power head, high power InGaAs, 38dBm

Manufacturer's part number :


Manufacturer Agilent Technologies

Keysight Technologies

Description :

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.

p>The 81628B is used with the threaded type adapters. When the adapter is removed, the 8 mm diametre 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.
