Patent ID: 7626709

Claim:
A device for examining the optical properties of surfaces comprising: at least one first radiation means emitting radiation at a first predetermined spatial angle to a surface to be examined; at least one first detector means for capturing the radiation emitted to and reflected back from the surface wherein said first detector means comprises an image-capturing component, allowing a local resolution of detected radiation, wherein said first detector means is positioned at a second predetermined spatial angle relative to said surface; at least one second detector means which detects radiation emitted to and reflected back from said surface to be examined, allowing an examination of at least one of an intensity and spectral characteristics of detected radiation, wherein said second detector means is arranged at a third predetermined spatial angle; and wherein said first, second and third spatial angles are each defined by a tuple of a first spatial subangle indicating a projection angle of a direction in space defined by a half straight line beginning in a point of origin in a Cartesian coordinate system onto an x/z plane perpendicular to said surface to be examined lying on an x/y plane, and a second spatial subangle indicating a projection angle of said half straight line onto a y/z plane perpendicular to said surface to be examined lying on the x/y plane; wherein said first and said second spatial angles are chosen such that a difference of said first and second spatial angles relative to said first and second spatial subangles is less than 50°.
