What is a vacuum coating system?

A vacuum coating system is a specialized technological setup designed for depositing thin films or multilayer coatings onto various substrates under meticulously controlled vacuum conditions. These systems typically operate at ultra-low pressures, often reaching 10⁻⁴ to 10⁻⁵ Pa or even lower. This high-vacuum environment is crucial for minimizing contamination, ensuring precise control over deposition parameters, and achieving high purity in the resulting coatings.

A typical vacuum coating unit comprises several key components: a robust vacuum chamber, various deposition sources (such as sputtering targets, evaporation boats, or electron beam sources), precise substrate holders and rotators for uniform film growth, and sophisticated control systems for pressure, temperature, and deposition rate. Integrated measurement tools, like quartz crystal monitors or optical monitoring systems, ensure exact film thickness and quality.

Key advantages of vacuum coating systems:

• Precise layer thickness control: Achieve sub-nanometer level accuracy, essential for advanced optical and electronic components.
• High reproducibility and film uniformity: Ensure consistent results and even coating across large substrate areas, critical for mass production and high-performance applications.
• Improved mechanical and optical durability: Create dense, defect-free film structures that significantly enhance the resilience and performance of coated materials.

These systems are vital in numerous sectors, including optics, laser components, microscopy, interferometry, electronics, and precision engineering.

Types of vacuum coating equipment

Meeting diverse industry demands requires a versatile range of vacuum coating equipment. Our portfolio encompasses various thin film deposition equipment types, each optimized for specific material properties and application requirements.

Sputtering systems

Sputtering systems are among the most popular and versatile types of vacuum deposition systems. This technique utilizes plasma to eject atoms from a solid target material, which then precisely deposits onto the substrate surface. This method is highly favored for its ability to produce highly uniform, dense microstructures and its capability for creating complex multilayer designs. Our sputtering machines are engineered to provide exceptional film uniformity with superior optical and mechanical properties, allowing for precise control over reflectance, transmittance, and polarization.

Other advanced deposition technologies

While sputtering is a cornerstone, we also support and integrate other advanced deposition methods:

• Thermal evaporation: Material is heated in a vacuum until it evaporates and condenses onto the substrate. Simpler than sputtering, it's effective for metals and materials with lower melting points.
• Electron beam (E-beam) evaporation: Employs a focused electron beam to precisely heat high-melting-point materials. This method is ideal for high-purity, complex oxide coatings.
• Chemical vapor deposition (CVD): Involves chemical precursors reacting or decomposing on a heated substrate surface to form a solid thin film. CVD is excellent for achieving conformal coatings over complex geometries.
• Atomic layer deposition (ALD): A highly controlled variant of CVD, where film growth occurs in self-limiting, layer-by-layer cycles. ALD offers atomic-scale thickness control and outstanding uniformity over 3D structures, making it perfect for ultra-thin coatings and nanotechnology.
