BO-SF Laser Optic with Stable Focal Position
For High-power Diodes, Fiber, and Solid State Lasers
The BO-SF laser processing optics from the Scansonic Scapacs® system is designed for industrial use where a stable focal position is critical. By using different object-to-image ratios, varying operational clearances and focus diameters are made possible. BO-SF easily integrates to a variety of applications, is high-efficient, has very good process stability, and produces great image quality.
Instead of using classical lenses the BO-SF shapes the beam by special mirrors to eliminate focal shifting. Like with 0.02 mm focal shift/kW-laser power this optic is effectively focal shift free.
BO-SF Features & Benefits:
- Practically free of focus shifting, even with high power and single-mode
- Safe for operating with a high-power laser output
- Tested up to 30 kW (with YLS-30.000 from IPG Laser GmbH)
- Easily openable for cleaning with clean air or gas before commissioning
- Triple-angled (or higher) construction has restricted bending (patent pending)
- Minimal dependence between focus position and contamination
