WSC-S Colorimeter dan Color Difference Meter |
Illumination geometric conditions of the instrument: o/d
Sample light source: Combination of CIE standard illuminant D65 and 10° wide viewing field, X10 Y10 and Z10.
Color representations:
(1) X,Y,Z; Y,x,y: L*,a*,b*; L,a,b: L*,u*,v*; L*,c*,h: andλd,Pe;
(2) Color-Difference:

(3) White
(a) Ganz whiteness: Binary linear whiteness recommended by CIE.
(b) Blue-light whiteness: W = B
(c) Tabble whiteness: It is recommended by ASTM (American Society for Testing and Materials); W = 4B-3G
(d) Reflection whiteness of R457
