Designed primarily for Nd:YAG at 1064nm, 532nm and 355nm, these diffraction limited zoom beam expanders offer variable magnification of 1-3X and 2-8X with adjustable focus to correct for laser beam divergence. Focus adjustment is provided that can also be used for divergence correction or collimation. C and T input/output mounting threads are compatible with Edmund Optics’ line of threaded mounting components, or mounting can be achieved using an optional mounting clamp. Please contact our Sales Department for custom magnification requirements.
