Our zoom beam expanders (or called as variable beam expander) are highly corrected 4-lens element systems with variable magnification from 1x up to 8x and Galilei-design.
We offer 3 types of beam expanders: fixed beam expanders, zoom beam expanders and motorised beam expanders at various wavelengths of 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.
The specifications of the lenses used in the beam expanders are:
Part number description: BEST-xxx-yy-T-AA
BEST --- BEST series beam expanders, zoom beam expanders.
xxxx------- laser wavelength: 10.6 means 10.6um, 532 means 532nm, 633 means 633nm.
yy -------- expansion ratio (magnification) in times
T ---------- type: T means adjustable/various/zoom beam expander; none means fixed beam expander.
AA -------- special purpose.
Example: BEST-10.6-3: 10.6um fixed beam expander, 3x.
BEST-10.6-3.5T: 10.6um zoom beam expander, max. 3.5x.
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.
Following is the beam expanders at the wavelengths of 405nm, 633nm, 808-980nm, 1550nm, 1850-1980nm.
