MLED test and measurement system

Edmund Optics has introduced an MLED modular LED test and measurement system. Available in three configurations for discrete LEDs, arrays, and assemblies, MLED test systems offer complete spectral measurements in compliance with CIE-127 design requirements. Data acquisition through the built-in USB port provides spectral, power, luminous flux, purity, and peak dominant wavelength information.

The MLED base system consists of a 2048-element CCD spectrometer, an internal calibration lamp with power supply, and a set of three calibrated neutral density filters to extend the system’s dynamic range. The unit also includes a Condition B intensity tube for ILEDB, 10cm CIE-compliant measurement of luminous intensity, spectral intensity, and all derived colorimetric information. The calibration lamp, traceable to NIST standards, is characterised for spectral flux and provides users with a simple, in-house method for system recalibration.

The CCD spectrometer uses a 2048-element CCD array and offers a resolution of 1.5nm with 0.5nm accuracy over a range of 350 to 1000nm. The detector is capable of measuring luminous flux to 200 lumens using the OD2 filter and measuring luminous intensity using the Condition B tube.
