WebThe focal length, f is given by the “lens makers formula”: (2.7) The transmission function is now: (2.8) This is the paraxial approximation to the spherical phase Note: the incident plane-wave is converted to a spherical wave converging to a point at f behind the lens (f positive) or diverging from the point at f in front of lens (f negative). WebIntroduction: Optics is a field in which light is studied, and the images that form through lenses using the light. Lenses can be used to refract light and create an image. The properties of the thin lens that characterizes it is the focal length (f) and the focal points.
