F-theta scan lens is also called flat field lens or the linear lens.The radial image heightequals to focal length of the lens
multiplied by the angle of the chief ray makes in the object space.While General focusing lenses deliver a focused
spot to only one point,They deliver a focused spot to many points on a scan field or workpiece.
The applications :Laser Marking; Engraving; Rapid prototyping; Drilling and Cutting systems .
