CS-200 - Spectral fitting method

Chroma Meter CS-200

CS-200 – CIE colour matching functions

• Spectral fitting method provides precise matching to the sensitivity of human eye and results with superior inter instrument agreement.

• CS-200 specification:– f1 = 1% (Class L is 2%)

Chroma Meter CS-200

Spectral sensitivity

• Why is matching to CIE Vλ curve (f1) that important?

• Photometric value is specified by the area of radiant energy which is covered by the Vλ curve.

• Ex. Illuminant A– All the red area

• Ex. LCD– Green area
