High Power Beam Expanders

Special Optics High Power beam expanders are specifically designed with a convex first surface, which diverges the return reflection from the first lens surface and prevents any damage backstream of the beam expander.

Note: Low Power beam expanders may have a return reflection that is not suitable with high power lasers.
