Our special designed Lens for Thick Glass Cutting focuses an incident single mode laser into a tight spot with 1.8 µm waist size along the entire Depth of Focus range (1-2mm typical range). The focused spot is equivalent to 0.35 objective NA and is ideally suited for thick glass cutting, such as flat panels. This module is a complete optical solution for cutting applications. There are no need for additional high NA objectives or other high cost optics. The Lens for Thick Glass Cutting module differs from standard EF elements by constant peak power along the focus region and requires low M2 and accurate input beam size.

Diffractive Multifocal (MF) lenses are widely used for glass cutting applications. In this process, multiple foci are formed along the cutting path, thus increasing the speed and accuracy of the process. To achieve optimal performances, small separation distances between neighbour foci and high-power densities are required. This is usually achieved with a high NA objective lens. However, the majority of off-the-shelf high-power objectives does not meet the application requirements and result in degraded performance. To address this issue, we have developed a tailored focusing module for glass cutting applications, by using a Multifocal lens. Our Multifocal module maintains diffraction limited spots size at all foci.
