Additive manufacturing has a great potential for modifying optics in a way that new functions, for example individual light distributions, could be realized by modifying the optical surface. The functionalization of the curved surface by multijet modeling is the goal of the 6D printing project (6D AF) at the Center of Optical Technology, Aalen University. To combine the coordinate systems of the printing unit, the printing table and the metrology unit a new photogrammetric position measurement system is developed and presented. First results of the accuracy in three axes are show and the improvement in motion is demonstrated.
This research is focused on the link between manufacturing parameters and the resulting mid-spatial frequency error in the manufacturing process of precision optics. This third publication focuses on strategies of avoidance and generation mechanisms of the mid-spatial frequency errors from the grinding process. The Goal is to understand the generation mechanisms of the mid-spatial frequency errors and avoid their appearance in the manufacturing process.
This research is focused on the link between manufacturing parameters and the resulting mid-spatial frequency error in the manufacturing process of precision optics. This second publication focuses on the parameters and the simulation of the grinding step. The Goal is to understand and avoid the appearance of the mid-spatial frequency error and to develop a simulation which can predict the resulting mid-spatial frequency error from a manufacturing process.
