Beam Expander

The beam expander can changes the beam’s size and divergence characteristics.

1.Use:  Beam expanders have numerous uses. By expanding a beam prior to focusing, smaller focal spot sizes can be achieved. Beam expanders improve a beam’s collimation. They are also used  to change the beam diameter To meet different requirements. Using a spatial filter with a beam expander can make an asymmetrical beam profile more symmetric and provide  more uniform energy distribution.

2.Features: 1.Low loss;  2.High-power operation;  3.Visible transmission.
