Applications of Coating Machines in Precision Optics and Problems Solved

        Achieve Ultimate Optical Performance: This is the core mission of coating machines, designed to precisely control the reflection, transmission and absorption of light.
        Improve Transmittance and Eliminate Ghost Images: By depositing anti-reflection coatings, surface reflection of lenses can be greatly reduced. For example, high-end coating machines can lower the reflectivity of lenses from the normal level of 0.5% to less than 0.1%, making camera imaging clearer and colors more realistic, while eliminating ghosting and glare common in camera lenses and VR glasses.
        Achieve Precise Spectral Control: Coating machines can deposit band-pass filters, cut-off filters, etc., to achieve accurate light wave screening. For example, in autonomous driving LiDAR, it ensures sensors only receive laser wavelengths and exclude sunlight interference; in 3D face recognition, it is used to precisely control invisible infrared light.
        Enhance Coating Stability and Reliability: Enable precision optical components to work stably in various complex and harsh environments.
        Strengthen Coating Density and Adhesion: Using technologies such as ion source-assisted deposition, coating machines can "press" the coating at the atomic level, making its structure denser and thus greatly enhancing adhesion to the substrate.
        Adapt to Harsh Environments: Solve the problems of easy peeling and wear of coatings. This ensures vehicle-mounted lenses do not crack under temperature changes, smart watch screens are durable, and aerospace optical components can resist space radiation.
        Coating for Curved and 3D Components: Lenses for mobile phone cameras and AR glasses are often 3D curved surfaces. New coating machines adopt technologies such as activated reactive sputtering to ensure high uniformity of coatings even on non-planar substrates, solving the challenges of complex optical path design.
        Large-Area and Continuous Uniform Coating: Maintaining uniform coating across large-size glass such as automotive central control panels and smart rearview mirrors is a major challenge. Advanced coating machines achieve high-uniformity coating on ultra-large sizes through self-developed magnetron optical deposition technology, increasing production efficiency by over 200% to meet the mass manufacturing needs of the automotive industry.
        Meet Ultra-High Precision Requirements for Multi-Layer Complex Coatings: Modern precision optical components often require dozens or even hundreds of thin films, with the thickness of each layer controlled at the nanometer level.
        Achieve Ultra-High Precision Monitoring: Traditional coating errors accumulate, while high-end coating machines equipped with direct optical monitoring systems can monitor coating thickness in real time online, meeting the deposition requirements of high-precision coatings with more than 200 layers. Some advanced direct optical control systems can reduce measurement errors from 0.5% to 0.01%, laying the foundation for manufacturing ultra-high-performance laser lenses and fluorescence filters.
