Beam Expander, Fixed Ratio, Nd:YAG, 1064nm

Manufacturer's part number :


Manufacturer Altechna


Description :

Galilean beam expanders are assembled using one diverging and one converging lenses, so there is no focal point inside the beam expander, thus it can be used for high powers. We offer beam expanders made from two, three, or more spherical lens made from BK7, FS, UVFS or other glasses which suit high power applications.
