Description

Details

F-Theta scanning lenses are specially designed system of lenses which are used to correct the scan-rate deficiency found in the standard flat-field scanning lenses. It is achieved by combining several lenses thereby creating a specific amount of barrel distortion. Therefore distance the spot travels across the flat focal plane are expressed as a multiplication result of scan angle theta and focal length. In that way scanning task is simplified and the need for electronic correction is eliminated. F-Theta scanning lenses in combination with galvanometer mirrors system and beam expander are ideal tool for laser marking, engraving and cutting systems.
