Expansion Optics Type 48EO

Expands the beam diameter of the collimated beam

The best fiber coupling efficiency for beam diameters <0.4 mm is achieved when the laser beam is expanded in advance.

This is done using the Schäfter+Kirchhoff beam expander type 48EO allowing lenses of longer focal length to be used, which improves polarization extinction, makes adjustment easier and increases coupling efficiencies.
