Benchtop Optical Power Meter for Optical Device Testing
The ADCMT 8250A provides high-resolution optical power measurement for R&D, production testing, and automated measurement of laser diodes, optical pickups, and optical drives.
Its low-noise design and high-resolution A/D converter provide a 5½-digit power display with resolution down to 0.1 pW or 0.001 dB. Automatic wavelength sensitivity correction is available in 1 nm steps.
0.001 dB
High-resolution relative optical power measurement
5½-Digit Display
Optical power display in mW, μW, nW, dBm, or dBr
390 to 1100 nm
Sensor-dependent wavelength coverage
Up to 200 mW
High-power measurement with compatible sensors
Nine compatible sensor configurations cover general-purpose, blue-violet, three-wavelength, and high-power measurement. Thin and cylindrical sensor shapes are available for optical pickups, confined measurement locations, fibers, and optical benches.
USB and GPIB interfaces are included as standard for integration into automated production and laboratory measurement systems. An analog output is also provided.
