New Zoom CO2 or YAG 2x to 8x diffraction limited Beam Expanders manufactured by WAVELENGTH TECHNOLOGY utilise a Galilei design for high powered applications. They are designed for powers <100 W, with variable magnification and adjustable divergence for a non collimated input. Also available are our attractively priced fixed beam Galilei expander range, covering 10.6 µm <150 W, 1064 nm, 532 nm and 355 nm suitable for medium power levels of up to 100 W. Both fixed and variable divergence models are available.
