Why Choose D25 Mirror Substrate?

EUV Lithography Systems: D25 Mirror Substrate with <0.1 defects/cm² ensure defect-free wafer patterning at 3nm nodes, a breakthrough for advanced semiconductor manufacturing. This ultra-low defect density prevents pattern distortions during extreme ultraviolet lithography, enabling the production of smaller, more powerful chips that drive next-gen computing and electronics innovation.
Semiconductor Metrology: λ/40 flatness enables sub-nm measurement accuracy in overlay inspection tools, critical for verifying chip alignment during fabrication. This exceptional flatness ensures precise dimensional checks, helping semiconductor manufacturers maintain strict quality control and meet the tight tolerances required for high-performance microchips.
High-Power Laser Optics: Boasting a 5x higher laser damage threshold vs. standard fused silica, these optics excel in high-intensity laser systems. They withstand extreme energy levels without degradation, making them ideal for industrial cutting, military directed energy applications, and scientific research where reliable performance under intense power is paramount.
Space & Defense Optics: Radiation-hardened grades survive LEO/GEO orbital conditions, enduring cosmic radiation and extreme temperature swings. These optics maintain stability in satellite sensors, missile guidance systems, and space telescopes, ensuring consistent performance in the harsh environment of space and critical defense operations.
