These beam expanders are specifically designed for applications where widened beam diameters are required. The larger the expanded beam, the smaller the structures can be produced with a paired F-Theta objective lens.

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.

Laserbeam expander

Jenoptik’s Fix-BEX product line offers the right solution for applications that do not require changes to the zoom factor.

Thanks to corresponding software interfaces, the motorized beam expander can be easily integrated into any system for laser material processing.

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.

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. 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 its reverse mode, the beam expander is threaded on both sides.

The BEX 2x-10x variable beam expanders for the wavelengths of 355 nm, 532 nm and 1030...1080 nm have a particularly large zoom range. All versions have an infinitely adjustable zoom factor between 2x and 10x.

The Fix-BEX 515...540 nm demonstrates its advantages for applications in the FIS sector. It has excellent directional stability and thus consistently offers high beam quality. Like all other versions, it offers a large input aperture of up to 8 mm (1/e2) and diffraction-limited imaging. Internal foci are prevented thanks to the sophisticated high-precision optic design. The divergence of the laser beam can also be adjusted. The optical elements are made of robust quartz glass with AR coating. In addition, the Fix-BEX can be used in reverse mode, as the beam expander is threaded on both sides.

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.

Doric Lenses now offers the two-photon laser scanning microscope range from the Hungarian company Femtonics.
