AR coatings

COATING WITH NARROW-BAND OR BROAD-BAND EFFECT FOR SUPPRESSING RESIDUAL REFLECTION

So-called AR, anti-reflective or anti-glare coatings are used in optics to suppress disruptive reflections at certain wavelengths or wavelength intervals. This process applies non-absorptive, dielectric layers to the optical elements to be rendered non-reflective. Reflections can be suppressed to < 0.5 % using PVD. Further reduction is possible with IBS coatings, down to < 0.2 % in the broad-band range and for some wavelengths, even down to 0.05 %.
