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 neighbor 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 do not meet the application requirements and result in degraded performance.
To address this issue, HOLO/OR has develop a tailored focusing module for glass cutting applications, used with a Multifocal lens. HOLO/OR’s Multifocal module (MF module) maintains diffraction limited spots size at all foci.
