We use the IBS coater to manufacture particularly complex coating designs with more than 100 layers. Ion beam sputtering (IBS) makes it possible to create very compact and homogeneous layers that retain barely any water and are thus extremely low drift. This combination makes the coatings insensitive to temperature fluctuations.
As a result, mirrors with reflections of R > 99.99% can be manufactured that are required for gyro applications or complex layer designs.
Thin-film polarizers and complex mirror coatings are now also available at 266 nm!
To date, IBS coatings have been available in the wavelength range from 400 nm to 3000 nm. A new coating material now makes it possible to create coatings in the spectral range starting at 260 nm. For the first time, complex mirror coatings are available in the standard wavelengths 266 nm and 355 nm in house, as well as thin-film polarizers in the UV range.
Coatings from 260 nm to 3000 nm
The new coating material can be used with all wavelengths between 260 nm and 3000 nm. The new material has already exhibited improved damage thresholds over the material used to date – as shown by measurements taken at the wavelengths 532 nm, 1064 nm, and 2 µm. At the wavelength 1064 nm (20 ns, 20 Hz), the damage threshold values were several times higher than those of conventional layers.
This new material holds the promise of an important advancement for many laser applications. Not only are the high damage thresholds and the wide wavelength range an improvement, but this new material promises the ability to produce novel and very specialized coatings.
