Fiber laser collimating lenses shape and stabilize the beam path inside the laser cutting head before it reaches the focusing lens. Proper collimation helps maintain consistent beam alignment, improves process stability, and supports clean, repeatable cutting performance across a range of materials and thicknesses.

Machinist’s Vault collimating lenses are manufactured from optical-grade fused silica and feature high-performance anti-reflection (AR) coatings optimized for fiber laser wavelengths. These coatings maximize laser beam transmission while reducing reflection and heat buildup during cutting operations.

Available in multiple diameters, focal lengths, and power ratings, our collimating lenses are designed for compatibility with a wide range of fiber laser cutting heads used across North America.
