Paper Abstract

We summarise a previously described method of economically manufacturing high precision aspherics by vapour deposition on infra-red materials. Then, on a specific lens example, we show the influence of two parameters (time of deposit and centering) on the final modulation transfer function. Finally, we introduce a set of orthonormal functions best suited to simulate aspherics for high aperture lenses.
