Custom-Sized Reflecting Mirrors (5-300mm) from China Suppliers - High-Quality Factory with UV Fused Silica
●Product Description
⚙️1. Core Functions
-
High Reflectivity:
- Metallic Coatings (Al, Au): Broadband 450–10000nm reflection (>95%, >98% in IR);
- Dielectric Coatings: >99% reflectivity at targeted wavelengths (e.g., 532nm, 1064nm).
- Beam-Splitting: Custom ratios (e.g., 50:50, 70:30) for laser combining or interferometry.
📊2. Technical Specifications
-
Substrates:
- UV Fused Silica: Low thermal expansion (0.55×10⁻⁶/°C), high LIDT (>5J/cm² @1064nm);
- Optional N-BK7, Sapphire for specific spectral needs.
-
Precision:
- Surface flatness λ/10 (@632.8nm), local error <λ/20;
- Diameter tolerance +0.0/-0.1mm, thickness ±0.2mm, clear aperture >85%;
- Parallelism ≤3 arcmin, surface quality 80-50 scratch/dig (upgradable to 20-10).
-
Coatings:
- Protective Layers: SiO₂ or Si₃N₄ coatings for environmental durability;
- High-LIDT Coatings: Compatible with femtosecond or CO₂ laser (10.6μm) systems.
🚀3. Applications
- Laser Cavities: High-reflective mirrors for fiber/solid-state lasers;
- Space Optics: Lightweight mirrors for satellite sensors with radiation resistance;
- Spectroscopy: Beam splitters in FTIR or Raman systems.
🛠️4. Customization
- Complex Surfaces: Flat, spherical (R10–5000mm), or aspheric (parabolic, hyperbolic);
- Custom Shapes: Circular, square, annular, or client-defined with tailored edges;
- Fast Turnaround: Standard orders in 10 days, special requests <4 weeks.
