The WG3010 is an integrating sphere optical power meter engineered for high-power and wide-dynamic-range optical measurement across the 700–1700nm infrared band. Unlike conventional photodiode heads that saturate under high optical power, its external integrating sphere probe spatially integrates total optical power, enabling a measurement range from 1μW up to 20W without the need for external attenuation—making it directly applicable to laser power characterization, high-power transmitter testing, and optical amplifier output monitoring. A 2mm InGaAs detector with 21 calibrated wavelengths (covering 850nm to 1650nm key windows) delivers 0.1dB accuracy and 0.01dB resolution, while the separated probe-and-display architecture allows the sphere head to be placed at the measurement point while the host remains accessible for reading or rack mounting. The 3.5-inch color LCD provides real-time mW/dBm/dB readout. USB and RS232 interfaces support remote control and integration into automated test platforms, including ATE systems requiring synchronized high-power optical measurement. At 205×205×100mm and ≤1kg, the compact host paired with a remote sphere head is purpose-built for lab benches, production floors, and system integration where conventional power meters cannot handle the power level.
