Abstract

Lightweight, athermalized mirror design remains a critical technology area for space-based applications, often requiring specialized optical evaluations not available in most commercial mechanical simulation software. The highest performing stiffening patterns require powerful CAD tools to parametrically model while maintaining continuity with complex solids, but integrating this engine with optomechanical analysis software requires extensive development from the user side. Lincoln Laboratory has created an API to accomplish exactly this, including full automation of the entire CAD to FEA to optical performance workflow. We have demonstrated this capability on a compact, off-axis beam expander with steep surface curvature subject to various gravity orientations and thermal loads, while studying the effect lightweight stiffening patterns on focus-subtracted wavefront error.
