For applications which require the highest reflectivity and damage threshold, with the lowest thermal drift, LASER COMPONENTS offers ion beam sputtering (IBS) coatings. Unlike other coating methods, our IBS chamber allows independent control of process parameters such as energy input, layer growth rate and level of oxidation. This results in highly homogenous and ultra-dense layers which are free of moisture. Due to the absence of moisture, IBS coatings are virtually drift free and are not sensitive to temperature changes.
This process control also allows the growth of very complex layers meaning that the highest level of performance may be achieved, including; reflectivity values as high as 99.99%, and very broad bandwidths. The high energy ion beam used in this process eliminates the need for high temperatures during coating, making IBS coating suitable for sensitive substrate materials. IBS coatings are available in the wavelength range of 260 nm to 3000 nm.
