We offer 3 types of beam expanders: fixed beam expanders, zoom beam expanders and motorised beam expanders at various wavelengths of 213nm, 266nm, 343-355nm, 405nm, 633nm, 515-545nm, 808-980nm, 1030-1090nm, 155nm, 1850-1980nm, 10.6um. Other wavelengths and custom-designed beam expanders are available upon request. For more information, please feel free to contact us.
We may use the following abbreviations in the tables: WL=wavelength, MAG=magnification, CA=clear aperture, CA1=input clear aperture, CA2=output clear aperture, D1=input diameter, D2=output diameter, L1=total length of beam expander, M1=connection or mounting thread, D=diameter.
BEAL is a zoom beam expander designed for automated applications. It combines multiple lenses to provide variable magnification and automated pergence adjustment from 1x to 6x. Driver and all the motors are integrated in the casing of the beam expander which makes it compact and convenient for usage. High pointing stability (<0.1 mrad) and fast magnification speed (1 sec from 1x to 6x) offers suitable performance for precision and high speed industrial applications.

Zoom beam expanders are ideal for systems in which different magnifications and precise control of laser beam pergence are required. We offer Galilean type zoom beam expanders with high LIDT AR coatings that minimize ghost reflections. Our zoom beam expanders allows to separately adjust magnification and pergence. Two main standard products change magnification in the range of 1x-4x and 2x-8x.

Our zoom beam expanders (or called as variable beam expander) are highly corrected 4-lens element systems. The version with pergence adjustment is very user friendly, as the magnification setting and the pergence setting are independent from each other, i.e. the pergence remains unchanged while changing the expansion factor. In addition, the total length of the beam expanders remain constant during zooming and/or pergence setting. For remote controlled setting, we developed motorized versions of our zoom beam expanders. A motor adapter can be incorporated to drive the mechanics used for magnification setting.
