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 on the specifications of the beam expander, but also on the laser beam parameters as well as the positions of the optical lenses
Beam Expander - 1064/532/355/405/266nm
Mounting Version for Beam Expander
Corresponding with Wavelength Technology's constant innovation and drive for excellence, they recently released their new beam expander mounting. This adjustable mount has been a widely accepted model that is able to compensate various degrees of input beam.
Now with the new mount, the operation of adjusting the first lens is more convenient. The user only needs to turn the center part of the beam expander and the first lens will move accordingly along the optical axis with no rotation.

Advantages
This mount also has advantage as the first lens does not rotate in respect to the second lens. It also has been equipped with scale for the user to measure the distance of the lenses.
