1 Chroma Meter CS-200 Next generation high performance instrument for measuring Luminance and Chromaticity of light sources.

2 Chroma Meter CS-200 A complete range of instruments Accuracy Price CS-100A Three filter type of Chroma Meter CS-1000A/S/TSpectroradiometer CS-200 Chroma Meter with spectral engine

3 Chroma Meter CS-200 CS Main features High accuracy: Spectral fitting method assures close matching to CIE sensitivity curves Wide measuring range: 0.01 to 20,000,000 cd/m² Portability: Compact Lightweight Battery powered 3 Measuring angles: 1°, 0.2°, 0.1° Small area measurement (0.1mm) Wide application range: Research & Development Quality assurance PC software: Standard accessory Professional version optional Various functions: Synchronized Measurements Selectable measurement speed USB connection to PC Large LCD display Data storage Optional accessories: Close up lenses ND filter Calibration plates for object mode Angle Finder Soft case

4 Chroma Meter CS-200 Composite Z sensitivity created by calculation Composite Y sensitivity created by calculation Composite X sensitivity created by calculation Spectral sensitivity of the CS-200’s 40 sensors CS High accuracy due to spectral sensor

5 Chroma Meter CS-200 CS Spectral fitting method CS-200 utilizes a photo diode array with 40 sensors Output data is corrected by adding coefficients for each sensor and wavelength position Peak wavelength : 430 nm Peak wavelength : 435 nm

7 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%)

8 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
