In an inspection module for inspecting optical parts ( ) for defects, especially contact lenses manufactured as injection-moulded parts, the optical parts ( ) are illuminated from one side and are observed from the opposite side by means of an image-resolving sensor ( ). The image data of the sensor ( ) are forwarded to image-processing means for identification of defects. To obtain a high throughput with a simple construction, a chain ( ) of liquid-filled vessels ( ) circulating in an endless line is provided. The endless line is passed in an inspection station ( ) between an illumination device ( ) and the image-resolving sensor ( ). Handling means in the form of grippers ( ) revolve with the vessels ( ), by means of which optical parts ( ) to be inspected can be introduced into the vessels ( ) at a position of the line upstream of the inspection station ( ) and the inspected parts can be taken out of the vessels ( ) at another position of the line.
