To prevent the disposal of minimally damaged lenses that fall outside the acceptable scratch and dig tolerance levels, an experimental study was conducted to repair mechanical scratches on a fused silica surface. The scratches were created using a di

In many conventional optical manufacturing processes, lapping is still a standard method to provide polishable surfaces. With the increasing use of CNC technology, efforts are being made to substitute the lapping process in the process chain. The pap
