This power head with cooled 5mm InGaAs detector provides highest accuracy performance from 800-1700nm.

The popular Keysight N7744A optical power meter with four power-sensor channels offer industry-leading solutions for device connectivity, high-speed measurement data acquisition and fast data transfer for post-processing.

These four-port optical power meters bring the highest performance in terms of sensitivity, noise and relative accuracy, like the 81634B modules, to the N77 instrument platform with large memory, fast data transfer and small footprint.
