D12.7 Mirror Substrate

D12.7 Mirror Substrate  Overview

The D12.7 Mirror Substrate is the cornerstone of high-reliability optical systems in satellites, laser targeting, and reconnaissance platforms. Crafted from ultra-low expansion materials like Zerodur® or radiation-hardened fused silica, it maintains <0.05×10⁻⁶/K CTE across -50°C to 150°C — perfect for environments where traditional optics fail.

Designed with aerospace-grade surface finishes (Ra<5Å), this substrate ensures minimal light scatter even under microgravity or high-G vibration. Whether you’re aligning mirrors for space telescopes or stabilizing laser paths in combat systems, its 12.7mm diameter (±0.001mm tolerance) delivers pixel-perfect precision.

Key Features

• Extreme Environment Resilience: Withstand lunar temperature swings (-180°C to +120°C) or desert sandstorms without warping, ensuring reliability in the harshest conditions. Our proprietary polishing achieves λ/10 flatness—8x smoother than standard aerospace optics—maintaining precision in lunar rovers, desert surveillance gear, or any environment where stability is non-negotiable.​
• Vibration & Shock Resistance: Survive 15G launch vibrations and 50,000-cycle thermal shocks, critical for aerospace and defense systems. The D12.7 Mirror Substrate’s 30 GPa·cm³/g stiffness-to-weight ratio prevents microcracking even in hypersonic flight, ensuring optical integrity in missiles, rockets, and high-speed aircraft where extreme forces are common.​
• Custom Coating Ready: Pre-optimized for ion-beam sputtered gold, dielectric, or anti-reflective coatings, enabling seamless integration with specialized finishes. Achieve >99.5% reflectivity with our PVD-compatible surface treatment, ideal for lasers, telescopes, and sensors where precise light control is essential for performance.​
• Military-Grade Durability: MIL-STD-810H certified against salt fog, humidity, and EMP interference, meeting strict military standards. Passes NASA’s 500krad radiation hardness tests, ensuring 10+ year reliability in LEO missions, making them perfect for defense systems and space-based optical equipment.

Applications

• Satellite Imaging Systems: Zero-distortion mirrors for 0.3m resolution Earth observation deliver crisp, undistorted imagery critical for disaster monitoring, urban planning, and agricultural analytics. These mirrors maintain precision across orbital thermal shifts, ensuring consistent detail capture even as satellites traverse extreme temperature zones.​
• Laser Targeting Modules: <2μrad beam steering accuracy in armored vehicle systems guarantees pinpoint targeting, even over long distances or rough terrain. This precision minimizes collateral damage in defense operations, keeping beams aligned despite vehicle vibrations or environmental interference.​
• Reconnaissance UAV Optics: 45% lighter than aluminum alternatives extend flight time by reducing payload weight, a key advantage for long-endurance surveillance missions. The lightweight design doesn’t compromise durability, withstanding harsh weather and high-G maneuvers while maintaining imaging clarity.​
• High-Energy Lasers: Handle 10kW/cm² IR exposure without thermal lensing, ensuring stable beam focus in industrial cutting, defense, and directed energy applications. This resistance to thermal distortion prevents power loss or target misalignment, even during prolonged high-intensity operation.
