Fix-BEX beam expander with fixed magnification
Fix-BEX beam expander 355 nm (UV)
High-power and ultrashort pulse systems
This beam expander is designed for a wavelength of 355 nm and offers a large input aperture of up to 8 mm (1/e2). It offers clear and stable laser power and can be used with a 1.5x, 2x, 4x or 8x expansion factor at high powers. The high-precision optical design ensures diffraction-limited imaging and prevents internal foci. It also comes with a divergence setting as standard.

High-power and ultrashort pulse systems
This reliable and powerful beam expander is ideal for both standard and high-performance applications. The Fix-BEX 1030–1080 nm comes out on top with its large input aperture of up to 8 mm (1/e2). The lenses are designed in such a way that light diffraction is limited so that image quality is achieved over the entire magnification range. This also prevents the occurrence of unwanted internal foci. It also comes with a divergence setting as standard. The housing is made of stainless steel for maximum resistance and durability, and the optical elements are made of robust quartz glass with AR coating. For use in the reverse mode, the beam expander is threaded on both sides.Zoom Factor | 1,5x | 2x | 4x | 8x |

Variable beam expander 1x-4x full quartz system
The BEX 1x-4x variable beam expanders for the wavelengths 355 nm, 532 nm and 1030...1080 nm provide a high image quality with their compact lengths. All versions are infinitely adjustable between a 1x and 4x expansion factor. The larger the expanded beam, the smaller that structures can be created with the paired F-Theta objective.
A focus ring allows the divergence of laser beams to be changed in a targeted manner, thus compensating for the focal length tolerances in the overall system. This also makes it possible to change the position of the working plane according to the scanning system.

Variable beam expander 1x-4x steadfast
The BEX 1x-4x steadfast beam expanders are characterized by a mechanical design that guides the movable optical elements in a stable, linear manner. This reduces the influence of mechanical manufacturing irregularities and increases beam stability whenever changing magnification and/or divergence. This ensures a beam direction stability of less than one milliradian.
Settings can also be conveniently locked. Therefore, influences such as vibrations or system accelerations system are minimized. In addition, the BEX 1x-4x Steadfast stands for easy maintenance and minimal set-up times.

Variable beam expander 1x-8x
The 1x-8x beam expanders are part of the SilverlineTM high-power lens series and are designed in such a way that a diffraction-limited image quality is achieved over the entire magnification range.
Optimized coatings ensure the highest transmission and lowest thermal influences. To ensure durability and a high destruction threshold in high-power laser applications, we use full quartz as the lens material.
