Key Takeaways Unmatched Lightweighting: Achieved a ≤ 40 kg/m² surface density and 90% weight reduction for large-aperture primary mirrors, setting a new benchmark in ultra-lightweight space optics. Superior Material Performance: RB-SiC mirrors outperformed Beryllium in thermal stability and specific stiffness, proving Reaction-Bonded Silicon Carbide (RB-SiC) as the optimal substrate for extreme space environments. AI-Driven Precision […]
Key Takeaways Aperture size is a fundamental parameter in optical system design and a primary driver of imaging and measurement performance. By enabling the collection of more light, larger apertures support higher spatial resolution, improved sensitivity, and enhanced signal-to-noise ratio (SNR). These advantages result in sharper imagery, more accurate measurement data, and greater overall system […]
Solutions for the Performance Boundaries of Large-Aperture Spherical Lenses Abstract In the era of rapid advances in optoelectronic technology, large-aperture spherical lenses act as the “core pupil” of modern optical systems. Their performance determines the imaging precision and beam-control capability of high-end equipment—from deep-space telescopes to nanoscale lithography systems. Achieving nanoscale surface accuracy on millimeter-scale […]
