Beam Expander - CO2 Laser 9.4/10.6 um
The most common type beam expander is derived from Galilean telescope which usually
has one negative input lens and one positive output lens. The input lens presents a
virtual beam focus at the output. For low expansion ratio, the Galilean telescope
is most often employed due to simplicity, small package size and low cost. Beam expander
is commonly used to magnify the laser diameter to be focused back in smaller spot size.

CO2 Beam Expander - Fixed Series
The most common beam expander is Galilean type which usually has one negative input lens and one positive output lens, the beam expansion ratio for a Gaussian beam depends not only the specifications of the beam expender, but also on the laser beam parameters as well as the positions of the optical lenses.
