Due to the hi-leveled double beam system being adopted, the measurement
with high accuracy and improved repeatability can be performed easily.
Total spectral properties can change not only combination of photopic
vision standard luminous efficiency V(λ) and CIE standard illuminant
D65 but standard illuminant A.
Full automatic instrument for the processing and control by using
a personal computer, allows always stable measurement data for all
sorts of calculations, average calculation or printer out-put.
