Konica Minolta's newly-developed spectral fitting method provides tristimulus values (XYZ = red, green, blue)
with significantly higher accuracy than that of conventional tristimulus colorimeters. This is achieved by using
the output from 40 sensors to calculate the spectral response corresponding to human eye sensitivity (CIE 1931
color-matching functions).
The CS-200 uses 40 sensors for sensitivity covering the entire visible region and multiplies each sensor output
by appropriate coefficients. This adjusts the spectral response of the instrument to close to the CIE 1931 color-
matching functions.
In additon to the 2 Standard Observer, the 10 Standard Observer (for object-color measurements) can also be
selected, which is impossible with conventional tristimulus colorimeters.

Accurate measurement
"Spectral fitting method" for accurate luminance &
chromaticity measurement.
KONICA MINOLTA's Chroma Meter for accurate light-source measurement
allows building of a color management network both internally and externally.
In R&D and design departments
There is no need for calibration work to determine a
value of each light source by using a reference
spectroradiometer. For displays like LCDs or organic
ELs in particular, user calibration for the reference
panel using a spectroradiometer can be eliminated
1
.
1 If higher accuracy is required, user calibration can be used.
In quality management and incoming
inspection departments
Since individual errors are minimized compared to
conventional tristimulus colorimeters, the inspection of
various devices such as panels does not require
individual error correction.
