Spherical lenses are core optical components for imaging, laser transmission, lighting and precision detection. Featuring curved spherical surfaces, they effectively converge or diverge light for cameras, telescopes, endoscopes, projectors and laser equipment.
Our ultra‑precision processed spherical lenses go through fine grinding, polishing and coating inspection, delivering low surface roughness, slight wavefront distortion and high uniformity. Stable across visible, near‑IR and partial mid‑IR bands, these standardized lenses integrate easily into modular systems for industrial inspection, research, medical and aerospace applications.
