Effective Laser Production for Multi-Spot Applications

Jenoptik provides machine integrators with pre-aligned optics, such as F-theta lenses and the compatible diffractive micro-optics. This enables them to respond more quickly to their customers’ needs while also increasing the efficiency of their systems. For example, for multi-spot applications, the same laser spots can be aligned with the workpiece with homogeneous energy input and consistent quality.

The advantages of compatible optics include almost lossless beam processing, improved performance of the laser production system, and precise manufacturing results.

As an OEM supplier with experience from a variety of projects in industrial laser production and the semiconductor equipment industry, Jenoptik is able to offer customized optical subsystems and components for specific applications: For example, for applications such as fine-metal masking, solar panel structuring, LED cutting, drilling and cutting of circuit boards, display production and laser material processing of plastics, metals, and glass. As diverse as the applications are, so too are the possibilities of combining different optical components and aligning them to the customer’s needs.

Customized Diffractive Optical Elements

Laser material processing applications rely on the use of diffractive micro-optical components to shape and split laser light. Depending on the application and requirement, beam shapers, and beam splitters can be combined with one another to create different spot geometries.

Beam splitters are commonly used in the industry in a lateral arrangement for the parallelization of laser beam. This facilitates multi-spot applications for the simultaneous processing of multiple workpieces. Other applications require spots to be aligned in the axial direction, in order to intensify the processing compared to applications with just one spot and to increase the cutting speed, for example.

Jenoptik offers its customers application-specific diffractive optical elements, such as focus shapers. These allow fast and efficient laser cutting in different layers of the substrate simultaneously, while also maintaining a homogeneous and precise laser spot. The optical design of the focus shapers allows for a wide range of applications through to 3D material processing.

In addition, Jenoptik also offers efficiency-enhanced e²® transmission gratings, which are not only used for pulse compression as in the laser source – thus increasing the efficiency of the laser – but also as beam combiners for laser diodes from UV to IR.

Thanks to its high-end manufacturing technologies, Jenoptik meets the exacting demands when it comes to accuracy and durability – even for high-power applications.

New F-theta Lens for UV Micro Material Processing

Jenoptik has added yet another UV lens to its JENarTM F-theta range for laser material processing: the new fused silica F-theta lens for 355-nanometer applications, with a focal length of 56 millimeters and a scan field of 22 millimeters. Depending on the application, the optics allow very small spot diameters up to 4.5 microns. The lens is specifically designed for use in micro material processing and for ultra-short pulse applications.

The F-theta lens range from Jenoptik fulfills the requirements of almost all standard methods for micro and macro material laser processing. Jenoptik’s F-theta Silverline series lenses are extremely robust and have a high damage threshold.

The adhesive-free mounting technology and assembly of the lenses in a certified clean room help to ensure that all lenses are highly durable and free from contamination. Jenoptik ensures its high quality standards by testing and measuring each lens individually. For applications which require a lens change due to product or process requirements, it is possible to replace the F-theta lenses without major adjustments to the laser system.
