Surface Roughness down to 3 Angstroms
3 angstroms. That’s only 0.0000003 mm!
That is the surface roughness to which Manx Precision Optics (MPO) polish their optics. Because when a laser doesn’t forgive, neither can your optics.
Polishing is a critical process in fabricating precision optics. Manx are proud of their setup because precision is the foundation of a quality component. Taking a surface from micrometer-scale roughness down to a sub-nanometer finish isn’t just a technical achievement, it’s critical for reliable optics for high-energy laser systems.
However, MPO go even further. MPO compensate-polish every substrate, accounting for the exact stress that the coatings will introduce before they’re applied. This delivers an optic with minimal wavefront distortion post-coating, while optimizing laser-induced damage threshold (LIDT) through superior surface quality and coating compatibility.
In high-energy laser applications, there’s no margin for error. A surface flaw invisible to the naked eye can become a catastrophic failure point under intense laser fluence.
The fundamentals matter. MPO never stop proving it.
