Handheld Optical Power Measurement for Production and R&D
The ADCMT 8230E combines portable optical power measurement with USB data acquisition for the development and production testing of laser diodes, optical pickups, and optical drives.
The meter supports four interchangeable optical sensors covering general-purpose and high-power measurement. Thin sensors fit optical pickups and confined measurement locations, while cylindrical sensors support built-in systems, optical benches, and optical-fiber measurement.
4½-Digit Display
Optical power measurement in W, dBm, or dBr
0.01 dB Resolution
High-resolution relative optical power measurement
Up to 200 mW
High-power laser measurement with compatible sensors
USB Interface
Direct digital data collection without a separate GPIB interface
General-purpose 82311B and 82321B sensors cover wavelengths from 390 to 1100 nm with a standard calibration wavelength of 780 nm. High-power 82313B and 82323B sensors cover the same wavelength range and measure optical power up to 200 mW with a standard calibration wavelength of 650 nm.
Automatic wavelength sensitivity correction is available in 1 nm steps. Eight measurement ranges can be selected automatically, manually, or remotely, and the meter provides both USB and analog outputs for production and laboratory systems.

Portable Optical Power Measurement
The handheld design supports optical power measurement in laboratories, production areas, and locations where a benchtop instrument is impractical.
General-Purpose Sensor Options
The 82311B thin sensor and 82321B cylindrical sensor cover wavelengths from 390 to 1100 nm and measure from 1 nW to 50 mW.
High-Power Measurement to 200 mW
Compatible 82313B and 82323B sensors measure high-power laser output up to 200 mW with a minimum specified beam-spot diameter of 0.1 mm.
1 nm Wavelength Correction
Automatic wavelength sensitivity correction adjusts the sensor response according to the wavelength setting in 1 nm increments.
USB Data Acquisition
The standard USB interface transfers digital measurement data directly to a PC without requiring an additional GPIB interface.
Eight Measurement Ranges
Select from eight optical power ranges using automatic, manual, or remote range switching.
Thin and Cylindrical Sensors
Thin sensors support optical pickups and confined spaces, while cylindrical sensors suit built-in systems, optical benches, and fiber measurements.
Analog Output
An analog output is provided in addition to USB connectivity for integration with recorders and production measurement systems.
