Paper Abstract

We design a TMA telescope for nanosat uncooled IR applications and manufacture one of its mirror using a ceramic 3D printing process. The TMA design serves as pretext to obtaining a very fast (N = 0.63) mirror to manufacture, we nonetheless gloss over a typical optical design workflow, with optical optimization, tolerancing and stray-light analysis. The metrology of the manufactured mirror will involve deflectometry, for which we give a bibliography. We manufactured one TMA mirror extracted from our design using laser stereolithography (SLA) 3D printing process for ceramic parts.
