Diamond turning is the powerful fabrication method for optics. Current process is very time consuming due to the lack of on-machine metrology. In this talk, we will first discuss the challenges and requirement of in-situ metrology, then we will present chromatic confocal on-machine metrology system developed in our lab and demonstrate its performance.
