Advantest Q82232 900nm-1650nm Optical Sensor

The Advantest Q82232 is a plug-in optical sensor module engineered for precision optical power measurement across the 900nm to 1650nm wavelength band. Built around a cooled InGaAs photodiode, it delivers measurement speeds up to 100 times/sec with noise performance of -94 dBm and dynamic range spanning -80 to +27 dBm. The sensor minimizes polarization dependence to 0.003 dBp-p or less, making it ideal for fiber-coupled optical testing, component characterization, and laser diode validation in both research and production environments.
