Camera Control for Eyeglass Grinding
During the grinding process of eyeglasses, the grinding result is continually analyzed. The eyeglass is illuminated by a laser and the resulting image is surveyed by two cameras from different angles of view. The Scheimpflug method (tilted planes of focus) is used for this application.

• Two standard CF 8/5 cameras are used. The sensor is tilted and provided with a specific filter glass. Due to space restrictions, the connection of the camera is moved from the rear to the side.

•  A frame grabber with an I/O trigger signal is installed for integration into the existing SPS control.

•  A customized electronic device has been developed for the galvanic separation, control signal level adaptation and camera power supply.

• The camera system comprises customized cables and a specifi c SDK for the adaptation to the customer analysis software.
