Atomic layer depostion is the ideal solution for many optical coating challenges.

Optical coatings

Optical coatings is a major application area for atomic layer deposition. Film uniformality, conformality and repeatability with the possibility of coating complex surfaces make ALD technology ideal for optical applications.

With the right choice of materials, good optical stack design and precise control of layer thickness, it is possible to build ALD coatings that alter the behavior of light in the desired wavelength range, be it IR, UV or visible light.

Thin film coatings can be used to improve the optical characteristics of objects and components in a multitude of areas, from LED illumination and micropore optics to lenses, wire-grid polarizers and diffractive optics.
