Grating spectroradiometer PMS-2000

for LED lighting

PMS-2000 DOUBLE-MONOCHROMATOR SPECTRORADIOMETER DOUBLE-MONOCHROMATOR SPECTRORADIOMETER WITH EXTREMELY HIGH STRAY LIGHT CONTROL LEVEL AND WAVELENGTH ACCURACY The design of PMS-2000 adopts the coaxial symmetry double-monochromator technique, realizing very high stray light control and wavelength accuracy. It is especially suitable for labs or research institutes with very high accuracy requirement. The Coaxial & Symmetrical Double-monochromator Technique The tested light is dispersed by the first grating and the second grating in sequence. The monochromatic light after two times dispersion goes into the detector. In this system, the two gratings are symmetrically set in one axis to realize coaxial rotation. It has super high wavelength accuracy because of no synchronous error.
