Variable beam expanders are ideal for systems in which different magnifications and precise control of laser beam divergence are required. We offer Galilean type variable beam expanders with high LIDT AR coatings that minimize ghost reflections. Our v

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.

BEST-W Series YAG Laser Zoom Beam Expanders (266/355/532/1064nm)

We are proud to present our new product. It is specially designed to cater for the various variable magnification of 2x up to 8x. It consists of adjustable pergence. These beam expanders are primarily intended for Nd:YAG, Green & UV lasers. They offer diffraction-limited performance at 1064nm wavelength.

  • For collimation of laser power<500kw/cm2

  • Variable magnifications 2x-8x

  • Galilei Design

  • Adjustable pergence
