Our Optical Glass Magnetron Sputtering Coating Line is a state-of-the-art vacuum deposition system designed for high-volume manufacturing of precision optical thin films. Utilizing advanced DC and Mid-Frequency Magnetron Sputtering technology, this production line delivers superior film uniformity, high adhesion strength, and precise control over layer thickness.
Unlike traditional thermal evaporation, this sputtering system excels at depositing dense, stable, and environmentally durable coatings on glass substrates. It is the ideal solution for manufacturers requiring high-throughput production of anti-reflective (AR) coatings, beam splitters, band-pass filters, and conductive transparent oxides.
Features & Technology
-
Multi-Chamber Configuration (Inline or Batch): Designed for continuous production, minimizing downtime and maximizing yield. The modular architecture allows for easy maintenance and process integration.
-
Advanced Magnetron Cathodes: Utilizes high-purity planar and rotatable magnetron cathodes. The system supports DC and Mid-Frequency (MF) sputtering modes, ensuring stable and arc-free deposition of both conductive and non-conductive materials.
-
Superior Film Uniformity: Engineered with dynamic substrate motion and optimized magnetic field distribution to achieve thickness uniformity of < ±2% across large-area glass substrates.
-
Precise Process Control: Equipped with PLC and PC-based automated control systems. Operators can manage multilayer stacks with high repeatability using Optical Monitoring (OMS) and Quartz Crystal Microbalance (QCM) feedback systems.
-
Low-Temperature Deposition: The magnetron sputtering process maintains low substrate temperatures, making it suitable for coating heat-sensitive glass and polymer-based optics.
Applications
This production line is specifically engineered to meet the rigorous standards of the optical industry:
-
Anti-Reflective (AR) Coatings: Deposition of multilayer AR coatings (e.g., MgF₂, SiO₂, TiO₂, Ta₂O₅) on lenses, displays, and cover glass to minimize glare and maximize light transmission.
-
Transparent Conductive Oxides (TCO): Production of Indium Tin Oxide (ITO) and Aluminum-doped Zinc Oxide (AZO) films for touch panels, LCD screens, and smart windows.
-
Beam Splitters & Mirrors: Fabrication of high-precision dielectric mirrors and beam splitters for laser optics and imaging systems.
-
Band-Pass & Edge Filters: Deposition of complex multilayer stacks for fluorescence microscopy, spectroscopy, and telecommunication devices.
-
Decorative & Functional Glass: Coating architectural glass with solar control films or low-emissivity (Low-E) layers.
