There are 2 types of beam expander: fixed and adjustable beam expanders. For the fixed beam expanders, the spacing between the two lenses inside the beam expander is fixed, but the spacing between the two lenses inside the adjustable beam expanders is adjustable. The lens material is ZeSe, which allows the red light to go through the beam expander.
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: /4
Surface Quality: 60-40 scratch-dig
Coating: HR dielectric coatings R > 99%

These beam expanders are designed specially for large pergent laser beam. Changing the distance between two lenses inside the beam expander can decrease the beam pergence to obtain better collimation of the laser beam. If they are used for large-pergence laser beam, you may turn the inner body to increase the spacing of two lenses and then to obtain better collimation laser beam. The material is ZnSe and thus the red light can go through the beam expander.
