AR structures

In the 1960s, it was discovered that the structures on the surface of moth eyes allow very significant reduction of light reflection.

Since then, this property has played a major role in many technical applications. This includes optics and display technology.

Antireflection structures

With laser interference lithography, temicon manufactures and supplies moth eye structures on surfaces up to a square meter.

  • In the visible spectrum from 400 nm to 700 nm, reflection is reduced to a value of about 0.2%.
  • Even for large incidence angles of 40°, the reflection is only about 0.5%.

Especially for lens systems made of polymer optics, in which many lenses are often arranged behind each other, anti-reflective coating to the surfaces brings decisive advantages.

Another advantage of functional surfaces with moth eye structures is their low production cost. No expensive vacuum process is needed — replication is done with an economical injection molding or roll-imprint process.
