Two established processes are being combined for this purpose: ultra-precise diamond drilling and targeted heating with laser beams (Laser Assisted Machining). By applying heat, the glass becomes locally ductile and can be machined with the diamond. This means that previously complex and multi-stage process chains such as grinding, lapping and polishing can be significantly shortened.
In particular, the IAP is investigating how the new process conditions affect the surface quality of the glass optics and how microscopic damage to the surface can be avoided. The new process is being tested experimentally on special demonstrators. This development promises not only shorter production times, but also precise optics with improved properties - an important step for applications in the optics industry.
