source equipment and provides more than 30 kinds of models.
Of special note, the maker is proud to be the top technology leading
company in the LED measurement field in the country, based on its wealth of
knowledge regarding machinery, electronics, optics, software and
commercialization capability. The maker’s integrating sphere system (OPI-1000) is strongly recommended among
its customers, in terms of its availability of custom-tailored production including producing various integrating
sphere systems with size of 30cm ~ 2m and aluminum appearance, internal coating with Barium sulfate and
number of ports is selectable based on customer requirements, It offers accurate measurement, including
correction of color error using a color correction filter, rapid integration time of 5~65,000msec, higher than
reflection rate of 97% (visible) and lower than diffusing light of 0.05% at 600nm. By using the product, the user can
measure such spectral characteristics as peak wavelength, medium wavelength, center wavelength, primary
wavelength, full width half max, CIE1931 color coordinate, CIE1976 color coordinate, correlated color temperature
and color rendering index.
