Our niche expertise and proven technology make FiveNine Optics a leader in Ion Beam Sputtered (IBS) coatings and ultra-low-loss optics. Components produced in our facility have demonstrated exceptional durability and performance in the field, addressing key industry challenges such as contamination resistance (FOD), size scalability, and long-term stability.

We currently produce best-in-class FOD-resistant high-energy-laser (HEL) coatings up to 750 mm in diameter, with 1 m capability coming soon. FiveNine Optics is also recognized as best-in-class for low-loss laser cavity mirrors, supporting the most demanding research in atomic physics and quantum computing.

IBS COATINGS

  • We specialize in Ion Beam Sputtered coatings. IBS coatings are spectrally deterministic, dense, durable, and exhibit the lowest losses and highest LIDT’s available.
  • We develop and operate revolutionary IBS machines to support a range of novel coating capabilities, including multi-band coatings for both low-loss and high-power applications.
  • FNO has made strides in overcoming issues that limited IBS coatings in the past: size, and LIDT (legacy perception does not put IBS at the top, current results do).
  • FOD resistant coatings have become vital to national security. FNO’s trailblazing performance has brought government-sponsored upgrades to our production capacity for large optics.

LOW-LOSS OPTICS

When every photon counts

  • Achieving Five-Nine performance (R > 0.99999) requires both a super-polished substrate and a low-loss IBS coating. FNO offers both.
  • FNO performs super-polishing in-house to maintain complete control over quality and throughput.
  • Our polishing process and metrology deliver best-in-class surface quality with sub-angstrom RMS roughness.
