Reflectance Materials and Coatings
Diffuse reflective materials. Synthetics (ODM) for the production of integrating spheres, laser resonators and reflection standards e.g. for calibration of spectral cameras or LiDAR applications. Barium sulfate coating (BaSO4) for integrating spheres and reflectors. Gold coating for NIR and IR spectral range.
Needs and Applications
Diffuse materials suitable for photonics must have special properties which even depend on the application. For example, integrating spheres, laser resonators or reflectance standards used in calibration or characterization of camera systems or spectral imaging systems must be particularly stable against aging, including UV aging. A robust surface is also necessary to simplify handling. Fluorescence free is as important as lambertian scattering and perfect homogeneity.
PTFE based Optical Material
Here we offer our high quality synthetic PTFE based ODM material, which can also be machined to customer specific shapes like integrating spheres. In addition, many gray-levels (reflectivity) of the material are possible. It can be used as a refelction standard and is also suited as a so-called target for LiDAR applications. Especially its good mechanical machinability, stability and handling are to be emphasized. These make it perfectly suitable for use in laser resonators or as a directly milled integrating spheres.
Barium Sulfate Coating
In addition to this bulk material, we also offer our liquid barium sulfate (BaSO4) material, which is mainly used for integrating sphere coating. This material is also fluorescence-free after aging, long-term stable, highly reflective and can be coated with the highest homogeneity using the production instructions provided.
Gold Coating
We also offer gold coated integrating spheres and parts which are espeically suited for the infrared (IR) spectral region.
