Product Name: High Precision CCD Spectroradiometer
Product NO: LMS-9000A/LMS-9000B
Brochure Download: pdf pdf


LMS-9000A/LMS-9000B is according to LM-79 clause 9.1. 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-9000B is quick test with high accuracy, it used in Scientific lab test. Due to the test speed and LMS-9000B can work with LSG-1600B/LSG-1800B/LSG-1900/LSG-2000 goniophotometer to do the Spatial color and Spectrum test.
