In the sixties it has been found that surface structures of a motheye show a significantly reduction of light reflection. This charateristic plays an important role especially for applications in optics or display technology.

temicon is able to master motheye structures by means of laser-interference-lithography up to sizes of 1 m².

  • Reduction of the specular reflection over the complete visible range of the spectrum (400 nm – 700 nm) down to 0.2 % only.
  • Even for large angles of incidence of 40° the reflection amounts only 0.5 %.
  • The technology of temicon is capable of producing motheye structures on curved surfaces as well as on free forms.

The advantages of antireflective surfaces are significant especially for polymer lens systems which usually consists of several lenses in sequence.

Beside the technical advantages motheye patterns can be replicated in a very cost efficient way. Instead of using very expensive vacuum processes the structures are produced at temicon economically by injection molding or UV-roll imprint.
