10.6um CO2 Laser Beam Expander ZnSe

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 ZnSe, which allows the red light to go through the beam expander.
YANNTEK could offer 3 types of beam expanders: Fixed Beam Expanders, Zoom Beam Expanders and Adjustable divergence angle beam expanders at various wavelengths of 355nm, 532nm, 1030-1090nm, 9.2-9.7um, 10.6um.
Other wavelengths and custom-designed beam expanders are available upon request. For more information, please feel free to contact us.
