Advanced Thin Films specializes in the most advanced coating technology available, ion beam sputtering (IBS coating), mastering the deposition of precise, dense, and durable films. We also have a full complimentary capacity of Ion Beam Assisted Deposition (IAD coating) chambers. Whether your needs are spectrally, technically, or environmentally demanding, Advanced Thin Films has the solution.
