Advantest Q82216 – Optical Sensor Head

The Advantest Q82216 is a dual-channel optical sensor head for precision optical power measurement and component testing. It delivers ±2.5% accuracy at calibration point with automatic wavelength sensitivity compensation, dual measurement modes (CW and 270 Hz±0.2% chopped light), and onboard data storage for up to 400 measurements per channel. The unit integrates a visual 11-dot level meter, configurable averaging (2–256×), maximum hold functionality, and GPIB data access, making it suitable for demanding laboratory and production test environments.
