Robust optical design and closed-form tolerancing through autodiff-based Hessian spectral analysis
Bastien Laville, Benjamin Aymard
Robust optical design demands quantitative knowledge of how manufacturing and alignment tolerances degrade system performance. We show that analysing the perturbation eigenmodes of…

The -achromat and beyond: a unified variational framework for optimal chromatic aberration correction
Bastien Laville, Benjamin Aymard
In this article, we present novel and effective methods for reducing chromatic aberrations in cemented lens systems. We derive an analytical solution coined the pentachromat, which…
