CMS-5000 Mechanical Spectroradiometer Test System for UV VIS NIR 

CMS-5000 mechanical spectroradiometer, fast auto adjust high-voltage not only make the measurement time quick, but also reduce the abrasion of the instrument. Measure the temperature in both environment and integrating sphere sphere simultaneously to make the data more visually and reliably. Figure of chroma and color difference in test can be exchanged freely. Color display and print relative spectral power distribution (UV-VIS-NIR) P(λ).

(2) Chromaticity coordinate:(x,y),(u,v)

(3)Correlated color temperature:(CCT)

(4) Rending index:Ra; Ri(I=1-15)

(5) Color difference (include international and national standards)

(6) Peak wavelength, half-width, radiating power

(7) Red ratio, green ratio, blue ratio(main wavelength, color purity)

(8) Luminosity data:luminous flux, correlated luminance

(9)Temperature:sphere temperature and environmental temperature (options)

The characteristics of CMS-5000 spectroradiometer 

1,The traditional mechanical scanning spectroradiometer has advantage of high wavelength accuracy, high sensitivity,small stray light

CMS-5000 principle:

Follow a similar operating principle:light passes through a slit and reflects off a collimating mirror to a diffraction 

grating, which separates the spectrum. A focusing mirror reflects the diffracted light onto the exit slit.
