Abstract
The increasing use of aspheres in a variety of optical systems has pushed the industry to become more efficient at its manufacturing processes. Non-optimized grinding techniques can cause excessive sub-surface damage and mid-spatial frequency errors which can be both time consuming and difficult to remove during polishing. The SCGa 100 grinder and SCPa 100 polisher provide unique platforms for asphere manufacturing. The SCGa 100 uses optimized kinematics to create a stiff and rigid platform which minimizes grinding errors and artifacts. Subsequently, polishing time on the SCPa 100 is decreased reducing the risk of altering the aspheric shape. This process improves surface quality while simplifying manufacturing.
