NEXCUT Fiber Laser Collimating Lens
NEXCUT fiber laser collimating lenses are designed for use in fiber laser cutting heads, where they convert the divergent laser beam from the optical fiber into a stable parallel beam before it reaches the focusing lens.
Manufactured from high-quality optical-grade fused silica and coated for fiber laser wavelengths, the collimating lens provides high transmission, low absorption and stable optical performance under continuous high-power laser operation.
Precision optical processing and coating help maintain consistent beam quality, reduce optical loss and support stable cutting performance.
A wide range of diameters and focal lengths is available for different laser cutting head models and power levels.

Function
The collimating lens is positioned between the fiber output and the focusing optics inside the laser cutting head.
Its main function is to convert the divergent laser beam into a parallel beam, helping ensure that the downstream focusing lens can accurately focus the laser energy onto the workpiece.
Stable collimation is essential for maintaining consistent focal characteristics, cutting quality and optical efficiency.
