BO-SF Modular Laser Optic with Stable Focal Position

The BO-SF laser processing optics from the scapacs^® modular system are designed for industrial use where a stable focal position is critical. BO-SF's design and construction ensure a high-quality beam with minimal power loss.

By using different object-to-image ratios, varying operational clearances and focus diameters are made possible. BO-SF easily integrates into a variety of different applications.

How BO-SF Works:

Instead of using classical lenses the BO-SF shapes the beam by special mirrors. They make the issue focal shift a non-issue, as with 0,02 mm focal shift/kW-laser power this optic is effectively focal shift free. That is how the process becomes much more stable, particularly with higher laser powers. To get more from the process the BO-SF contains a patent pending diffraction limitation, a plus to reach greater efficiency.

If the process does not work as it should, the BO-SF does with an emergency operating feature made possible by the mirrors, which are unsusceptible to gradual contamination and smaller weld penetrations.

BO-SF Product Features:

• Practically free of focus shifting, even with high power und single mode
• Safe for operating with high-power laser output
• Tested up to 30 kW (with YLS-30.000 from IPG Laser GmbH)
• The system can be opened by removing the protective glass, which enables the system to be cleaned (e.g., with clean air or gas before commissioning).
• Triple-angled (or higher) construction has restricted bending (patent pending).

BO-SF Product Advantages:

• High level of process reliability - with practically no shift
• Higly efficient process - with very good image quality
• Very good process stability - with a long-lasting, stable focus position
• Minimal dependence between the focus position and contamination

Excellent emergency-operations functionality, with water-cooled mirror. Thus functionality on the optical surfaces is guaranteed, even with gradual contamination or small weld penetrations.
