IBS Mirror Coatings

08 May 2018

Alongside our industry familiar E-beam coatings, offered since 1986, LASER COMPONENTS

now has Ion Assisted Deposition (IAD) and Ion Beam Sputtering (IBS) coating capabilities.

Being an extremely 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

extremely 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 248nm to 3000nm.
