The beam expanders are designed and coated at the laser wavelengths of 1064nm 532nm 355nm and 632.8nm respectively.These Beam expanders are widely used in laser scanning and marking systems.

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:

  • Material: BK7 fine annealed, fused silica and ZnSe depending on laser wavelength.

  • Diameter: -0.1mm

  • Thickness: ±0.1mm

  • Flatness: lamda/4

  • Surface Quality: 60-40 scratch-dig

  • Coating: HR dielectric coatings R > 99%

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 beam expander; none,means fixed beam expander. Here adjustable means that the distance between the inside 2 lenses is a little adjustable. The"adjustable" may change the beam divergence anlge a little.

  • 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.

BEAL Series Beam Expanders (1064/532/355nm)

Our beam expanders are assembled using one perging and one converging lenses. As there is no focal point inside the beam expander, it can be used for high powers. Special treatment of lenses and mechanics is performed for UV application to improve lifetime and LIDT of the expander. Standard magnifications are from 1.1x to 10x. Beam expanders for any wavelengths between 266 - 2000 nm are available upon request.

Features

  • Custom magnification and design on request

  • Extended lifetime and LIDT for UV applications

  • Inpidual reports of beam ellipticity, M2 and pointing stability parameters

  • Custom wavelengths are available in the range of 250-3000nm

Standard specifications:

YBE Series Beam Expanders for 1um Lasers

YBE series beam expanders are intended for low power (500W) lasers such as Nd:YAG and Yb doped fiber lasers operating near the 1um wavelength. The beam expanders are of Galilean design and use multi-spectral Zinc Sulphide for the optics which has an absorption at 1um of 0.0005cm-1 (similar to ZnSe at 10.6um). ZnS also has 20 times the thermal conductivity of Fused Silica and a higher refractive index. The refractive index allows a two element design to be used rather than three elements.

Dimensions85mm long, 46mm maximum diameter
Focusing+/-3mm lens spacing from infinity position corresponding to approximately +/-1.5m focusing distance respectively.
Turning the focusing ring translates the lens without rotating it.
CoolingAir-cooled.
Output aperture30mm diameter (all magnifications).
FittingsM30x1.0 thread on input for 4.7mm length, M43x0.5 thread on output for 5mm length.
