High-quality substrate selection: Laying the foundation for spherical optical performance
Our Single-sided Ultra-smooth Spherical Mirror Substrate is crafted from premium optical materials such as fused silica (JGS1/JGS2) and low-dispersion optical glass (H-K9L), providing outstanding optical homogeneity and mechanical stability. Fused silica variants excel in the UV to NIR spectral range (180nm-2μm) and are resistant to high-power laser damage. making them ideal for laser focusing applications. H-K9L substrates provide cost-effective performance for visible-range systems with good transmittance and low chromatic dispersion. The substrate blank undergoes strict quality control to eliminate bubbles, inclusions and internal stress, ensuring consistent spherical curvature and focusing performance across the entire functional surface.
Super-precision processing technology:
Achieving nanometer-level smoothness and precise curvature
Our single-sided ultra-smooth spherical mirror substrate is manufactured using advanced super-precision processing technologies, including chemical mechanical polishing (CMP) for the spherical surface and precision grinding for the flat back surface. The spherical surface achieves an ultra-low roughness of <0.1nm RMS, minimizing light scattering and ensuring optimal adhesion for subsequent coatings. The curvature radius is controlled within ±0.005mm, and surface accuracy reaches λ/10 @632.8nm, ensuring precise light focusing into a sharp focal point. The flat back surface features a flatness of λ/5 @632.8nm for stable mounting without tilting, while edge chamfering (0.3-0.6mm×45°) prevents chipping during coating and handling.
