Understanding the Role of an F-theta Lens

An F-theta lens is a specialized optical lens used in laser marking, engraving, cutting, and drilling systems. Its key function is to maintain a linear relationship between the laser scanning angle and the position of the laser spot on the working surface. This ensures that the laser remains in focus across the entire scan field, delivering consistent processing quality from center to edge.

LaserChina’s F-theta lens designs are optimized for a wide range of laser wavelengths, making them suitable for fiber lasers, CO₂ lasers, UV lasers, and green lasers. This versatility allows seamless integration into diverse industrial laser systems.
