WebLenses whose thickness is not negligible are sometimes called thick lenses. The thin lens approximation ignores optical effects due to the thickness of lenses and simplifies ray tracing calculations. It is often combined with the paraxial approximation in techniques such as ray transfer matrix analysis. Focal length Web6 Jul 2010 · A real lens has axial thickness, two radii of curvature, one for each surface (front and back), as well as some non-zero edge thickness. The line connecting the two centers of curvature is the optical axis. Thus far, we have disregarded the axial thickness of a lens by making it zero ( t = 0). swedenborg clinic
