We have a new webpage explaining the basic functionality in SimuLens for simulating lenses a variety of ways. Click here to check it out.
Progressive Addition Lens Anatomy
With digital lens surfacing (a.k.a freeform) one or both surfaces of a lens can be completely specified by the Lens Design System (LDS). For example the LDS can provide a height map, giving points on a grid of some chosen
Zernike Polynomials
Truncated expansions such as Zernike polynomials provide a powerful approach for describing wavefront data. However, many simple calculations with data in this form can require significant computational effort. Important examples include recentering, renormalizing, and translating the wavefront data.
