Product Name: CCD Spectroradiometer
Product NO: LMS-8000A/LMS-8000
Brochure Download: pdf


LMS-8000A/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, colourimetric and radiometric applications.

The LMS-8000AS/LMS8000S is updated on LMS-8000A/LMS-8000. It can connect with two integrating spheres: the big one is for LED luminaries and the small one is for LEDs & LED modules. The software can be chosen between the two integrating spheres to test. This new technology can save a lot of time and length the use life of the optical fibre & detectors, click to the blog page for more information: Technology advanced for LMS-8000 CCD Spectroradiometer
