Key Features That Redefine Precision

• Dual-Side Ultra-Smooth Finish: Achieve Ra ≤0.2Å roughness on both surfaces for flawless light reflection, eliminating wavefront distortion in high-end optics. This exceptional smoothness ensures uniform light transmission, critical for applications like advanced microscopes and lithography systems where even atomic-scale imperfections could compromise performance.​
• Thermal & Chemical Stability: Built with fused silica, ULE® glass, or custom ceramics to withstand extreme conditions, resisting thermal expansion and chemical corrosion. Ideal for industrial furnaces, semiconductor etching tools, and harsh-environment sensors, these materials maintain integrity across wide temperature ranges and aggressive chemical exposures.​
• Zero Defect Guarantee: Scratch/dig ≤10/5 per MIL-PRF-13830B standards ensures minimal surface flaws, meeting strict military and aerospace quality requirements. This level of perfection prevents light scattering in defense optics and satellite sensors, guaranteeing reliable performance in mission-critical applications where failure is not an option.​
• Custom Sizes & Shapes: Diameters from 50mm to 450mm, thicknesses from 0.5mm to 15mm, cater to diverse system designs—from compact laser modules to large telescope mirrors. This versatility allows seamless integration, reducing assembly complexity and optimizing optical performance in both small-scale devices and industrial-grade systems.​
• EUV/DUV Compatibility: Optimized for next-gen lithography and metrology systems, these components excel in extreme ultraviolet and deep ultraviolet wavelengths. Their precision ensures accurate light manipulation, enabling the production of 3nm and smaller semiconductor chips, a cornerstone of advanced computing and electronics innovation.
