A multiple-order diffractive engineered surface (MODE) lens is an optical component that is ideally suited for photon-starved astronomical applications. For example, the Nautilus Array, a proposed space observatory for high-fidelity exoplanet detection and characterization, will utilize an array of MODE lenses to achieve unprecedented light collection area. Despite this potential, work is necessary to advance MODE manufacturing capabilities from current laboratory prototypes to production levels that are required for successful technology insertion. Accordingly, we present the first formalized production-level MODE manufacturing process and first analytically validated model of MODE production. Specifically, an integrated model for the MODE production cost, schedule, and risk was constructed utilizing Monte Carlo simulation. This model was utilized to simulate and analyze the production of 35 MODE lenses—the Nautilus baseline. We applied queuing theory to the Monte Carlo model to improve MODE production through optimizing manufacturing variables. Future system architects, engineers, and managers should utilize this integrated model and optimization methodology to shape MODE production. Overall, this research serves two consensus civil space industry priorities for the 2020s—exoplanet detection missions and advancing programmatic and technical readiness in tandem—through improving MODE actualization and offering a general methodology applicable to emerging optical technology production. |
