Chromium Thin Film Disk
Chromium Thin Film Disk is a precisely fabricated form designed for high-performance coating, optical, and sensing applications where uniformity and controlled thickness are critical. Known for its hardness, corrosion resistance, and stable optical properties, it provides excellent adhesion to various substrates, making it a reliable choice in demanding environments. The thin-film disk format enables integration into sputtering systems, precision optical assemblies, and sensor platforms. Industries such as microelectronics, optics, and data storage employ chromium thin film disks for protective coatings, reflective layers, and functional surfaces with tunable electrical and optical characteristics. Specific technologies benefiting from this product include microalgae detection sensors based on spectroscopic ellipsometry, high-density optical data storage media, and thin-film transistor coatings. Research focuses on optimizing deposition parameters, microstructural control, and thickness tuning to enhance performance in both optical and electronic devices. Combining durability, adaptability, and precision, chromium thin film disks remain indispensable for advanced materials engineering and innovation.
