A thin lens is an optical element with zero thickness that has refracting power. It is almost always used in air (n = n' = 1.0) and is characterized by its focal length f. An object at infinity is imaged to the Rear Focal Point of the lens F'.

We assume a negligible translation of rays inside the lens. The thickness function is . is the maximum thickness. (2.1) The transmission function of the lens is ... In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces. Lenses whose thickness is not negligible are sometimes called thick lenses. The thin lens approximation ignores optical effects due to the thickness of len… nbox テールランプ前期後期
