Abstract
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 (sodalime 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.
