High-Resolution Handheld Optical Power Meter
The ADCMT 8230 provides high-resolution optical power measurement for the development, production, and automated testing of laser diodes, optical pickups, and optical drives.
Nine compatible optical sensors cover general-purpose, blue-violet, high-power, and three-wavelength measurement. Thin, cylindrical, and wide-area sensor configurations support optical pickups, confined measurement locations, optical benches, fibers, and high-NA lenses.
5½-Digit Display
High-resolution optical power measurement in W, dBm, or dBr
0.001 dB Resolution
Precise relative optical power measurement
Nine Sensor Options
General-purpose, blue-violet, high-power, and three-wavelength sensors
405 / 650 / 780 nm
Supports Blu-ray Disc, DVD, and CD laser measurement
Blue-violet sensors provide a flat sensitivity characteristic around 405 nm. Three-wavelength sensors support 405 nm, 650 nm, and 780 nm laser measurements, while high-power sensors measure optical power up to 200 mW.
The standard USB interface allows direct digital data acquisition from a PC and supports automated production systems without requiring an additional GPIB interface. An analog output is also provided.
