Optical Diffuse Reflecting Materials
for different optical applications

Barium Sulphate (BaSO4)

Based on high-purity Barium Sulphate BaSO4, we produce a ready-to-use white reflective coating. We offer this optical white in various containers depending on the size of the surface to be coated. This liquid is normally sprayed onto the carrier to be coated. We also offer the complete sprayer with container. However, this kit is recommended only for smaller to medium-sized surfaces.

Coating Service for Diffusive Reflecting Surfaces

We offer our diffusive reflecting surface coating services with Barium Sulphate for “all” optical applications. These services range from recoating existing, used products (e.g. recoating of integrating spheres) through coating individual components or systems to coating large batches.

Optical Diffusive Reflecting Material

The optical diffusive reflecting material “OptoPolymer” is a plastic that is used in numerous photometric applications because of its highquality production, purity, and highly diffusive reflectance behaviour. Our material has also gained acceptance among many users in optical metrology. The following advantages make “OptoPolymer” indispensable in the optical industry and research.


  • Useful wavelength range: 250 nm – 2.500 nm
  • Reflectance: ≥ 98,5 % in the visible and 93 % in the wavelength range 250 – 2.500 nm
  • Density: 1.5 g/cm3
  • Temperature range: min. -200 °C to max. +260 °C
  • Hardness: 30-40 Shore D
  • Water solubility: Insoluble
  • Resistance to chemicals: High
  • Flammability: Non-flammable under UL class V-0
  • High UV stability
