Fused silica spherical lenses are produced from amorphous silicon dioxide with extremely low impurity content and high structural uniformity. The spherical surface is generated through precision grinding and polishing to achieve controlled curvature and surface smoothness. The material exhibits low thermal expansion coefficient and high resistance to laser-induced damage. Optical behavior remains stable across ultraviolet to near-infrared wavelengths, making it suitable for high-energy optical environments and precision imaging systems.
