Anti-Reflection


 
Anti-reflection structures are structures on a surface that reduce the reflection from the surface compared to the bulk material.

 
The anti-reflection structures can be applied directly to any formable material like thermoplastics or UV curable materials by nanoimprint lithography or roll2roll or it can be defined on non-formable materials by nanoimprint lithography and subsequently transferred to the material by etching. The anti-reflection effect is achieved by modification of the surface topography on a sub-wavelength scale.

 
NILT anti-reflection structures make use of the bio-inspired moth-eye effect to create a 3D sub-wavelenght surface topography, resulting in a graded refractive index profile which reduces the reflection of the surface.
