Spectrophotometer LMS-8000

LMS-8000 LED Measurement System is an automated measurement system 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.

The LMS-8000S can connect to two integrating spheres: the big one is for LED luminaires and the small one is for LEDs & LED modules. The software can be chosen between the two integrating sphere to test. This new technology can save a lot of time and lengthen the use life of the optical fiber & detectors, click to the blog page for more infomation: Technology advanced for LMS-8000 CCD Spectroradiometer
