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.

Zoom-type Laser Beam Expanders
Optical system used when expanding the input laser beam to have its collimated beam.
- After adjusting focus, expansion ratio can be set linearly without change in housing length.
- Easy to change the expansion ratio by replacing beam expanders with minimal alignment.
| Wavelength | Expansion ratio | Product name | Housing size | Maximum input beam diameter | Maximum output beam diameter | Total Transmission |
|---|---|---|---|---|---|---|
| 1064nm (fused silica) | x0.8 to x3 | EPZ-13S | φ25 x 64(+3/-0.6)mm | φ4 | φ12 | over 96% |
| x3 to x7 | EPZ-37S | φ25 x 64(+3/-0.6)mm | φ3.0(x3) to φ2.2(x7) | φ9.0(x3) to φ15.4(x7) |
