A testing device for detecting defects of transparent test specimens, in particular of ophthalmological lenses, has an illumination device for transilluminating test specimens to be examined and with an image acquisition device for imaging the test specimen transilluminated by the illumination device. The illumination device includes a plurality of linearly adjustable light sources for generating a stripe pattern. To capture the stripe pattern, the acquisition duration of the image acquisition device can be adjusted in such a way that the light emitted by each of the light sources is detected as a light stripe. Further, the disclosure relates to a testing method for detecting a defect of a transparent specimen.

Testing device and testing method

A device and method for the controlled processing of at least one workpiece (), comprising a workpiece carrier () on which at least one workpiece receptacle () is present remote from a rotary shaft (), at least one processing unit () and at least one inspection unit (), which are offset relative to the rotary shaft () by an angular distance (&#x3b2;) from one another, are each arranged so that they can be adjusted and moved in a translational manner radially with respect to the rotary shaft (), so that a processing beam (E) and an inspection beam (P), offset relative to one another by the angular distance (&#x3b2;), describe the same spiral-shaped movement path (S) relative to the workpiece carrier (), and the inspection results derived at an inspection point (P) are used to control process parameters in order to change the effect of the processing beam (E).
