BO-SF | Stabilized Focus Positioning up to 30 kW

FEATURES

• Practically free of focus shifting, even with high power and single

mode

• Safe for operating with high-power laser output

• Tested up to 30 kW (with the YLS-30.000 from IPG Laser GmbH)

DESCRIPTION OF FUNCTION

The BO-SF laser processing optics (from the scapacs®modular system) are
designed for industrial use where a stable focal position is critically
important. Its 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. Thus, the
BO-SF can be easily integrated into a variety of different applications.

CHARACTERISTICS

• High level of process reliability – with practically no shift

• Highly efficient process – with very good image quality

• Very good process stability – with a long-lasting, stable focus pos.

• 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.

• The system can be opened by removing the protective glass, which

enables the system to be cleaned (for example, with clean air or gas
before commissioning).

• Triple-angled (or higher) construction has restricted bending (patent

pending)
