Bei einem Farbmessger\u00e4t bezieht sich Geometrie auf die Art und Weise, wie Licht auf die Oberfl\u00e4che eines Objekts trifft und reflektiert wird, sowie auf den Winkel, unter dem die Farbmessung erfolgt. Die Wahl der Geometrie beeinflusst die genaue Messung der Farbe, da verschiedene Oberfl\u00e4chen unterschiedliche Reflexionseigenschaften haben. <\/p>\n

What is meant by the term “diffuse\/8\u00b0”? In a device with a diffuse\/8\u00b0 geometry, the sample is illuminated diffusely, meaning light is scattered from all directions. The observer receives the reflected light from a position that is 8\u00b0 to the normal (perpendicular) to the sample surface. The diffuse\/8\u00b0 geometry is also known as “sphere geometry” because a sphere with a white interior coating is used for light projection. Multiple reflections inside the sphere lead to color mixing. The 8\u00b0 deviation of the observer from the sample surface allows for reflection measurement with or without gloss inclusion in some HunterLab devices. In the gloss-inclusion measurement mode (RSIN), the total reflection, meaning both diffuse and specular reflection (direct reflection of the light beam, mirror-like reflection, or gloss), is measured. In the gloss-exclusion mode, only the diffuse reflection is measured. The gloss component is eliminated by opening part of the sphere from which light is normally directly reflected from the sample to the receiver.<\/strong> <\/p>\n","protected":false},"excerpt":{"rendered":"
