Glass exhibits excellent optical transmittance in the visible spectrum (400-700 nm). Therefore, it is widely used in optical systems such as laser projection and light delivering. In this study, an ultraviolet laser system was combined with a high-speed galvanometric scanner unit to mill optical glass materials. First, a numerical simulation approach was used to evaluate the effect of the bite distance of milling. After the laser milling of optical glass materials (soda-lime and B270 glass), the surface morphology, surface roughness, and cross-section quality were analyzed using a three-dimensional confocal laser scanning microscope to evaluate the effects of milling parameters on optical glass materials.
