IBS mirror coatings for moisture sensitive substrates


Alongside its E-beam coatings, LASER COMPONENTS now has Ion Assisted Deposition (IAD) and Ion Beam Sputtering (IBS) coating capabilities. Being a precise and highly replicable method, IBS coatings are used for the most spectrally demanding applications, such as steep edge dichroic mirrors and very broad band mirrors.

Unlike other coating technologies, process parameters such as beam energy, layer growth rate and oxidation level, can be individually regulated to a high precision during the coating process.

The result is an optical coating with high density and low thermal drift, due to the absence of moisture retention. IBS coatings exhibit low scattering losses and extremely high reflectivities, greater than 99.99% depending on optimised wavelength.

This is a ‘cold’ coating method, and thus is suitable for temperature and moisture sensitive substrates.

LASER COMPONENTS offers custom IBS coating in the wavelength range 248-3,000nm.
