NVSR-2000 Night Vision Spectral Radiance Meter
NVIS weighted radiance is better than 1.7*E-11W/(cm2 *sr* nm)
Typical application scenarios
NVSR-2000 Night Version Spectral Radiance Meter can measure luminance, radiance(IR), NVIS weighted radiance for night version products in VIS-NIR region, relative spectral power distribution, chromaticity coordinates((x,y),(u’,v’)), CCT, CRI: Ra,Ri(i=1～14), SDCM, peak wavelength, FWHM, purity, dominant wavelength, red ratio, etc. Measurement range covers from 380nm to 950nm. It has high test accuracy and powerful software analysis functions,which is strong in line with the requirements of many domestic and foreign standards such as MIL-STD3009 and GJB1394-92.
Main characteristics
1.Integrated multi-function
Integrate multiple functions in one, powerful measurement functions: including luminance/radiance, relative spectral power distribution, chromaticity coordinates, CRI, SDCM, peak wavelength, FWHM, purity, dominant wavelength, red ratio, etc.
2.High sensitivity
The equipment adopts the array detector of constant temperature refrigeration, which realizes the extremely low luminance measurement capability of 0.003cd/m2 and the ultra-wide luminance measurement range.
3.High accuracy
No V (λ) mismatch error, and the measurement accuracy is high.
