The d/8° geometry has two different principle of measurement. With our without gloss trap.
The integrated gloss trap allows measurements with and without gloss exclusion
Spin Mode (SCI Specular included) the gloss trap is closed. Both the colour and gloss components are measured. Spex Mode (SCE Specular excluded) The gloss trap is open and gloss component escapes the sphere, which means the measurement is made without the gloss part.It is possible to measure all the reflected light (colour and gloss) or only the colour (without gloss)
