Dah Young Vacuum specializes in optical and hard coating technologies, offering intelligent, high-throughput, and highly stable coating solutions.
In the optical field, we provide both evaporation and sputtering systems, integrated with three proprietary smart platforms to optimize the entire process—from film thickness simulation to real-time process monitoring. Our solutions are widely applied in eyewear, lenses, displays, lasers, and medical optics.

For hard coatings, we utilize advanced PVD processes to create functional films with high hardness, excellent wear resistance, and corrosion protection. These coatings are extensively used in machinery, tooling, and semiconductor components to enhance service life and process reliability.

We welcome your inquiries and look forward to supporting your coating needs.
