Functional Optical Coatings

Dielectric and Metallic Coatings for Optical Components

Our core competence at Bte Bedampfungstechnik and Born Coating is the coating of optical components for technical applications. We use innovative coating designs to modify the physical surface characteristics of glass, plastics, and metals. In this way, we influence the reflection, transmission, and emission behaviour to meet the requirements of your application. With thin dielectric and metallic layers, we realise high-precision adjustments of the optical surface characteristics. 

Our optical coatings serve to reflect, guide, and filter light, enhancing the properties of optical components to meet your exact specifications.

Our Optical Coatings

Mirrors

Mirrors are manufactured by depositing a metal layer or by employing dielectric layer systems. These coatings are also known as highly reflective (HR) coatings. 

Filters

Filter layers are necessary for many applications in optics. Optical filters are used to select the incident radiation according to certain criteria. The primary influencing variables are the wavelength and the angle of incidence.

Beam splitters 

Dielectric beam splitters serve the purpose of separating light into its reflected and transmitted components. They are utilised when light of a particular wavelength or spectral range requires division into a reflected (R) and a transmitted (T) component, with one part being transmitted while the other is reflected. 

ITO

Indium Tin Oxide (ITO) coatings are designed to produce an electrically conductive surface while maintaining high transparency in the visible spectral range. Due to the semiconductor properties of this material, ITO is also effective in reflecting long-wave IR radiation.

Plastic coating 

We offer various coatings for plastic components, such as anti-reflective coatings, mirrors, or layers for filtering and splitting light beams.
