This line is a high-performance, multi-layer anti-reflective (AR) coating solution specifically engineered for Magnetron Sputtering Systems. Designed to maximize optical transmission while ensuring superior durability, this turn-key solution is ideal for architectural glass, display covers, solar panels, and high-end optical applications.

By utilizing reactive sputtering processes, it deposits precise metal oxide layers that create a destructive interference effect, virtually eliminating surface reflections across the visible spectrum.

Key Features & Benefits

  • Ultra-High Transparency: Achieves a peak light transmission of >96% and an average reflection of <1% across the 420nm to 680nm visible range.

  • Multi-Layer Engineering: Utilizes alternating high and low refractive index materials (e.g., Nb₂O₅/TiO₂ and SiO₂) to create a broadband anti-reflective effect.

  • Excellent Uniformity: Formulated for the high precision of magnetron sputtering, ensuring layer thickness uniformity of ±1.5% across large substrate areas.

  • Superior Durability: The fully inorganic coating is hard, dense, and resistant to abrasion, humidity, and thermal cycling. It passes MIL-C-48497A and ISO 9211 standards for environmental durability.

  • Ease of Integration: Compatible with both DC and Mid-Frequency (MF) reactive sputtering processes, offering stable deposition rates and minimal arcing.

Typical Coating Structure

The standard solution employs a 4-layer or 6-layer design to flatten the reflection curve:

  1. Substrate (Soda Lime, Borosilicate, or Display Glass)

  2. Layer 1: Medium Index Layer (Adhesion Promoter)

  3. Layer 2: High Index Layer (e.g., Nb₂O₅, TiO₂, Si₃N₄)

  4. Layer 3: Low Index Layer (e.g., SiO₂)

  5. Layer 4: High Index Layer

  6. Layer 5: Low Index Layer (Final Protective Capping Layer)

Note: Custom layer stacks are available for specific substrate refractive indices or color requirements.

Target Materials (Consumables)

Our solution is optimized for use with high-purity planar or rotary targets:

  • Silicon (Si): 99.99% for SiO₂ reactive deposition.

  • Niobium (Nb) or Ti (Ti): 99.9% for high-index layers.

  • Ceramic ITO: Optional for static dissipation if required.

Applications

  • Architectural Glass: Storefronts and windows to reduce glare and improve energy efficiency.

  • Display Technology: Touch panels, LCD/LED protection covers, and museum glass.

  • Solar Energy: Cover glass for photovoltaic panels to maximize light absorption.

  • Automotive: Dashboard displays and HUD (Head-Up Display) glass.
