Abstract
Disclosed are systems and methods for scoring and separating a glass sheet along a curved trajectory using a laser and optics. The system includes a laser that generates a laser beam, a focusing lens, and a conical optical component, such as a conical lens or a reflective conical mirror. The laser directs the laser beam through the focusing lens and conical lens to create a curved score line that is projected onto a glass sheet to create a curved score line, along which the glass sheet can be separated. Optionally, the laser directs the laser beam through the focusing lens towards a conical mirror, off of which the laser beam is reflected toward the glass sheet to create a curved score line.
