Apparatus for inspecting a material provided with a coated surface, preferably glass, with a light source disposed above the surface, which emits light in a predetermined wavelength range in the direction of the surface, and a first camera (11, 11', 11", 14'), wherein the first camera (11, 11', 11", 14') is configured to determine a color value of the detected light, wherein the first camera (11, 11', 11", 14') is disposed above an inspection line located on the surface inclined to the light source in such a way that it sees the specular reflection of the light emitted by the light source from the coated surface in the region of the inspection line, and has a first aperture angle in such a way, that light of the light source reflected from a first point of the inspection line is separately detectable at a first viewing angle and from a second point of the inspection line spaced from the first point is separately detectable at a second viewing angle, wherein the first viewing angle and the second viewing angle are different, wherein the first camera (11, 11', 11", 14') is configured such that it determines a first color value of the light reflected from the first point and a second color value of the light reflected from the second point, wherein an evaluation device connected to the first camera (11, 11', 11", 14') is provided, which is configured to compare the first color value and the second color value in each case with a specific, predetermined color setpoint value or with a specific, predetermined color setpoint value range or to compare a difference of the first color value and the second color value with a specific, predetermined color value difference setpoint value or with a specific, predetermined color value difference setpoint value range, predetermined color value difference setpoint value or with a specific, predetermined color value difference setpoint value range, wherein the at least one second camera (12, 12', 15') being provided, the second camera (12, 12', 15') likewise is configured to determine a color value of the detected light, wherein the second camera (12, 12', 15') is disposed above the inspection line located on the surface and inclined to the light source, wherein the second camera (12, 12', 15') has a second aperture angle such that light of the light source reflected from each point of the inspection line is detectable, preferably simultaneously, by the first camera (11, 11', 11", 14') and by the second camera (12, 12', 15'), wherein the first camera (11, 11', 11", 14') and the second camera (12, 12', 15') are configured such that they each determine the color value of the light reflected from each point of the inspection line, wherein the evaluation device connected to the first camera and the second camera is configured such that it uses the color values of the first camera and of the second camera at each point of the inspection line for a comparison with the specific, predetermined color setpoint or the specific, predetermined color setpoint range, the evaluation device is further configured such that it evaluates the color value of the reflected light from different points of the inspection line additionally as a function of their associated viewing angle.
