High Precision CCD Spectroradiometer

LMS-9000C High Precision CCD Spectroradiometer/spectroradiometry is according to LM-79 clause 9.1. It is designed for any visible optical spectrum distribution analysis, mimicking various light sources in the visible region by feedback control of the radiant power emitted by individual LEDs. This LED optical spectrum analyzer will be used as a transfer standard for photometric, colorimetric and radiometric applications.

LMS-9000C can do quick test with high accuracy. It used in scientific lab. It works with integrating sphere and standard lamp as a system: LPCE-2 High Precision Spectroradiometer Integrating Sphere System.
