The AQ23291A is an optical sensor head for measuring optical power over a wavelength range of 800 to 1700 nm. Its large-area InGaAs detector supports measurements of light from single-mode fibers, multimode fibers, and free-space optical sources.
The sensor head can be positioned close to the device or optical source under test, providing flexibility for optical component evaluation, multi-fiber connector testing, and measurement setups where direct access to the optical signal is required. The AQ23291A is used with the AQ23202A Interface Module in an AQ2300 Series Test Platform.
