25 Feb 2013 AR coatings are applied at moderate temperatures of ~100ºC, but for some components, such as crystals and GRIN lenses, these temperatures can have an adverse effect on the substrates causing discolouration or even damage.
Ion beam sputtering (IBS) coatings open up new possibilities for process temperatures below 100°C. LASER COMPONENTS offers broadband coatings for temperature-sensitive optics. In the case of GRIN lenses, it is possible to achieve an average reflection of <1.5% across the 400-1000nm spectral range. This allows a large wavelength bandwidth and large differences in the angle of incidence to be compensated for.
