Antireflective treatment

By SILSEF

At SILSEF, we create antireflective treatments by embedding nanostructures into a substrate or a thin film applied to its surface. These structures replicate the “moth-eye effect,” functioning as an adaptive index layer. This layer simulates a low optical index at the nanostructure tips, which gradually increases to match the substrate’s index. This technology allows an effective anti-reflexion treatment on a wide spectral band and a large range of incident light angles. It can be applied on large surface, plane or curved and on a wide range of materials.
