AQ23295A Optical Sensor Head (Si)

Large-Area Si Sensor Head for Short-Wavelength Optical Power Measurements 

The AQ23295A is an optical sensor head for measuring optical power over the short-wavelength range from 400 to 1100 nm. Its large-area Si detector supports stable measurements of light from single-mode fibers, multimode fibers, and free-space optical sources.

The handheld sensor head can be positioned close to the device under test, making it suitable for optical device evaluation, multi-fiber connector testing, and measurements in setups where direct access to the optical signal is required. The AQ23295A is used with the AQ23202A Interface Module in an AQ2300 Series Test Platform.
