IBS coat optical element: UV wavelength high output compatible laser mirror
This is a mirror that is resistant to damage from high-energy UV lasers due to IBS coating.
Manufacturer: OPTOMAN (Lithuania) To achieve a high reflectivity in the ultraviolet wavelength range, it is necessary to effectively control scattering and absorption losses. For UV laser users, mirror degradation is a significant issue. OPTOMAN has focused on surface quality and optimized coating technology. This technology protects optical elements from UV lasers and extends their lifespan.
