Precision Manufacturing of Large-Aperture Spherical Lenses
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 components represents one of the greatest challenges in optical manufacturing.
