AR-Structures
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 manufacturer of 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 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.
