LMS-8000A/LMS-8000AS Array CCD Spectro-photometer is used for identifying the performance of individual LED. It is designed to have a capability of producing any visible spectral distribution, mimicking various light sources in the visible region by feedback control of the radiant power emitted by individual LEDs. This LED test system will be used as a transfer standard for photometric, colorimetric and radiometric applications.

LMS-8000AS is updated version for LMS-8000A, LMS-8000AS can connect two integrating spheres at the same time. That’s mean LMS-8000AS be switch between the two spheres conveniently, but no need to take out the detector cable and optical fiber between the big sphere and small sphere.

Measures:
• Colorimetric: Total Radiant Intensity, Dominant Wavelength, Peak Wavelength, Color Coordinates, Half-Bandwidth, Spectral Purity, Correlated Color Temperature (CCT), Color Rendering Index (CRI).
• Photometric: Total Luminous Flux (Lumen), Luminous Efficiency, Radiant
• Electrical: Forward Voltage, Reverse Voltage, Forward Current, Reverse Current, Voltage, Current, Power, Power Factor.
