NVSR-2000 Night Version Spectral Radiance Meter is a spectroradiometer that measures spectrum,color,luminance,radiance,and night vision radiance for night version products in VIS-NIR region.It has high test accuracy and software analysis functions,which fully meets the requirements of many domestic and foreign standards such as MIL-STD3009 and GJB1394.

Main characteristics

1)Measure parameters at  the visible and infrared wavelength, such as luminance,radiance, the night vision weighted radiance NVIS value, relative spectral power distribution P (λ); chromaticity coordinates (x, y), (u ', v'); correlated color temperature: Tc ; Color rendering index: Ra; Ri (i = 1 ~ 14) (special calculation R15); color tolerance; peak wavelength, half width, purity, dominant wavelength; red ratio and other parameters.

2)Wavelength range cover 380-950nm

3)The weighted calculation of the night vision radiance value is in accordance with  requirements of GJB1394-92 and the night vision imaging system compatible aircraft interior lighting standard
