An apparatus for examining optical properties of surfaces which have effect pigments, with a first radiation device which is configured to irradiate radiation in a first irradiation direction characterized by a first irradiation angle onto the surface to be examined, and with a first image recording device which is configured for recording a spatially resolved image of the surface irradiated by the first irradiation device, characterized in that the apparatus has a second image recording device which is configured for recording a spatially resolved image of the surface irradiated by the second radiation device, and an evaluation device which is configured to evaluate the image recorded by the second image recording device in order to determine at least one property which is characteristic of the effect pigments and/or of individual effect pigments.
An apparatus for examining optical properties of surfaces that contain effect pigments, with a first radiation device which is configured to irradiate radiation in a first irradiation direction (R1) characterized by a first irradiation angle (a1) onto the surface to be examined, and with a first image recording device which is configured for recording a spatially resolved image of the surface irradiated by the first irradiation device,
A method for examining optical properties of surfaces and, in particular, surfaces provided with effect pigments, wherein a first radiation device irradiates radiation in a first irradiation direction (R1) characterized by a first irradiation angle (a1) onto the surface to be examined, and a second radiation device irradiates the surface to be examined with radiation in a second irradiation direction (R1) characterized by a second irradiation angle (a2), and a first image recording device records at least one spatially resolved image of the surface irradiated by at least one of the irradiation devices
