Method and device for the optical testing of objects, components and / or workpieces made of or with transparent material, in particular of those with their own structure, preferably for testing headlight glasses, the objects mentioned being irradiated with test light and by material and / or surface Inhomogeneities or errors generated after the primary light has been masked out essentially in the direction of radiation (forward scattered) scattered or diffracted light with spatially synchronous assignment between the area of the object penetrated by the test light and a photosensor or the like. received scattered light is used for error detection and evaluation, characterized in that a region to be examined in each case of the transparent material of the object, component and / or workpiece with a small cross-sectional area, in particular having a substantially punctiform cross-section, preferably parallel-bundled test light beam, in particular test laser beam, shines through is scanned. |
