Holmarc’s variable beam expanders are based on Galilean design. This 5-element diffraction limited design allows continuous beam expansion within the specified range. The expansion ratio can be adjusted by rotating the zoom control. Holmarc’s variable beam expanders are equipped with broadband AR coated lenses and aluminium casings.
