● Measure the color and chromatic aberration reflected by the object
● Measure D65 brightness (R457 blue light whiteness)
● Measure the degree of fluorescent whitening produced by the emission of fluorescent substances (the sample contains fluorescent whitening agent)
● Measure CIE whiteness (Gantz whiteness W10 and color cast value TW10)
● Measure the whiteness of ceramics, building materials and non-metallic mineral products
● Measure Hunter System Lab and Hunter (Lab) whiteness
● Measure yellowness, ink absorption value
● Measure the opacity, transparency, light scattering coefficient and light absorption coefficient of the sample
