WHITE BALANCE CHART (70% REMISSION)

REFLECTANCE

The TE115 chart is designed for white balance. The density of the white area is 0.15 (based on

BaO 4S=0). This corresponds to a remission of 70%.

The material which is used for the white chart shows high homogeneity of the remission in the

visible spectrum of 380 to 700nm (see gray curve in the illustration). In the area below 420 the

remission shows a steep decrease. In this area the sensitivity of the blue and red functions is

so low, that the light reflected is not transformed significantly.
