CL-500A ILLUMINANCE SPECTROPHOTOMETER

Compact illuminance spectrophotometer. Measures tristimulus values (XYZ), chromaticity (Ev xy, Ev u'v', Ev, dominant wavelength, excitation purity), correlated colour temperature, ?uv, general and special colour-rendering indexes (Ra and Ri), spectral graph, peak wavelength, rank and colour difference (?(XYZ), ?(Ev xy), ?(Ev u'v')), with a relative spectral response within 1,5% of the CIE spectral luminous efficiency curve V(?) and temperature/humidity drifts limited to +/-3%. Can be stored at temperatures within the -10 to 45°C range.
