Using high-fidelity opto-mechanical simulations and executing on experimental strategies to characterize optical stability, drift, noise sources, and scaling limits, ranging from back-of-the-envelope calculations to detailed finite element analysis (FEA) encompassing tolerance stack-ups, thermal behavior, structural stiffness, and vibration sensitivity. Designing components for opto-mechanical integration of precision components and assemblies supporting lasers, optics, vacuum-integrated components, state-of-the-art sensors, high-speed photodetectors, DMDs, SLMs, AODs, and EOMs.
