Features:
1. Focusing Lens
- Function: Focuses the collimated parallel laser beam onto the workpiece surface to form a high-power-density spot.
- Features:
* High transmittance (>99% ,1064nm Typical)
* Low absorption rate to reduce thermal effects
* Multi-layer AR coating
* High damage threshold, suitable for kW-level lasers
* Various focal lengths (125mm, 150mm,155mm, 200mm, etc.) available
* Applications: thick plate cutting, precision welding
2. Collimating Lens
- Function: Converts the divergent laser from the fiber into a parallel beam to ensure stable and consistent focusing.
- Features:
* Low divergence angle, ensuring beam quality
* High power resistance, suitable for 1kW–30kW lasers
* AR-coated to minimize power loss
* Various focal lengths (75mm, 100mm, etc.)
* Improves processing stability and prevents focal shift
