Abstract

We present transmission increased fused silica lenses produced by using self-organized antireflective structures for which we developed an efficient manufacturing process. The spectral transmission measured over the whole lens aperture shows a significant transmission enhancement of up to 3.5% in the UV range. Local measurements on the lens’s surface reveal a strongly reduced reflection of below 0.1% for $300\mathrm{nm}$ wavelength, which is homogeneous over the whole lens. Further, the lenses show a broadband spectral antireflection behavior. For $600\mathrm{nm}$ wavelength the reflection was measured at about 1%.
