    Example: of the product model number FT-355-255-158 described the working wavelength is 355nm, the effective focal length is 255mm and the scan field is 158mm * 158mm.

          F-Theta lenses are commonly used in laser marking,engraving, and cutting systems. F-Theta lens are designed to providea flat field at the image plane in the scanning system. The scan radial imageheight equals to focal length of the lens multiplied by the angle of the chiefray makes in the object space. The formula as follow:


    2y’=EFL×2θ×π/180


     where2y’ is the scan length or diagonal, EFL is the focal length of the scan lens, 2θ is overall scan angle.
