Beam Expander

Application notes: Why do we develop Adjustable divergence beam expander? When the entrance laser beam is an idealized parallel beam, it will be focused at the ideal focal position after being expanded and focused. However, as the entrance laser beam is usually divergence in nature, it focus at a location deviated from the ideal focal position after being expanded and focused. By adjusting the distance between two lenses, adjustable divergence beam expander focuses the laser beam at the required position such as the focus point or at other position in order to meet the practical working distance requirement of the laser operation such as laser marking.
