PearlCutTM is a laser process solution for precision cutting of glass components in any shape, including undercuts. Ultrafast laser pulses and a dedicated beam shaping ensure that the substrate is cut with highest precision and high quality edges, in just one process step. At cutting speeds of about one meter/second, the PearlCutTM process maintains an accuracy level of just a few μm.
Applications include free shape cutting of thin glass parts for mobile electronics and display substrates and cover glasses, yet the process is also suitable to separate thicker glasses for other applications.
Processable glass types include soda lime and chemically strengthened glass with any ion-exchange depth. In addition brittle transparent materials such as sapphire can also be processed. The PearlCutTM process for laser glass cutting works non-ablative and kerf-free. As a result, no dust is created during the cutting process. The resulting smooth edges ensure high bending strength of the cut parts.
