To adjust the diameter of a laser

Laser Beam Expanders

High performance Laser Beam Expanders, realized by combining lens design techniques with anti-reflective coating technology.

Overview

We have a diverse lineup, including those for fundamental waves of Fiber Laser and YAG Laser, SHG and THG, fixed magnification and zoom type.

Features & Strengths

Point1 Low wave front error design

Point2 Very compact size, all fixed beam expanders use the same housing

Point3 Easy to adjust for beam divergence

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.
