Lenses for laser scanning optical systems

F-Theta Lenses

High performance F-Theta lenses, realized by combining lens design techniques with anti-reflective coating technology

Overview

Diverse lineup, including options for fundamental waves of Fiber Laser and YAG Laser, SHG and THG, focal lengths, scan areas and color correction.

Features & Strengths

Point1 Superior optical design for minimal spot variation

Point2 Optimized design for diffraction limit

Point3 Wide scan area

Applications

Laser marking

Laser marking, a technique for writing letters, symbols, and bar codes without ink.
Our lenses can be utilized in optical systems for laser scanning.

Laser processing

Lasers offer increasingly high output. They can be used for engraving, cutting, drilling, melting, 3D modeling and many other processes.
Depending on the application, the performance required of optical systems also varies. We will propose and design the optimum lens for your needs.
