Mechanical Beam Expanders

TOPAG offers beam expanders with different expansion ratios and wavelengths. Newly available is the beam expander series VEX which stands out by its very compact design and the excellent pointing stability. If only one expansion ratio is required, fixed beam expanders are a cost-effective solution.

Continuous Zoom Beam Expanders

TOPAG offers different manually adjustable zoom beam expanders. For small expansion ratios, the clear input aperture will limit the possible input beam diameter. For large expansion ratios, the clear output aperture is the limiting factor. Please choose your zoom beam expander accordingly. The VEX beam expander models provide better pointing stability. All models are available with different coatings, please tell us the required wavelengths when ordering.

 

Fixed Ratio Beam Expanders

Whenever only a fixed beam expansion ratio is required, these expanders will be the cost-effective choice. Different expansion ratios and wavelengths are available.
