Custom-Sized Reflecting Mirrors (5-300mm) - High Reflectivity UV Fused Silica from China Suppliers and Factory

ALHAZEN offers custom-sized reflecting mirrors with diameters ranging from 5 to 300mm, crafted from high-quality UV fused silica substrates. Our mirrors boast a remarkable surface flatness of λ/10 and a reflectivity exceeding 99%, making them perfect for full-reflective or beam-splitting applications. Designed to operate efficiently across a wide wavelength range of 450 to 10000nm, these mirrors are ideal for use in lasers, aerospace optics, and scientific research. As a leading factory and supplier in China, we are committed to providing superior optical solutions to meet your needs

Product Detail

●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.

●Differentiation Highlights

● Ultra-Broadband Compatibility: Gold (Au) coatings cover 800–10000nm IR for thermal imaging or FIR lasers.

● Extreme Environment Stability: Fused silica substrates withstand -200°C to 400°C for deep-space missions.
