IBS Mirror Coatings

19 Jun 2017

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.
