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.
