White reference reflection standard for calibrating and measuring

We offer Restan as a reflectance standard in a circular metal case with 50 mm diameter which is suitable for all spectroscopic and densitometric applications. Individual calibration is available on request.

Restan

Our PTFE (Polytetrafl uoroethylene) based RESTAN diffusely reflects more than 98% of light in the area between 300 nm and 1700 nm. This means the reflection level is higher and more uniform, especially at longer wavelengths than the reflectance of barium sulfate (BaSO4). The material is stable long-term, temperature consistent, workable, available in various sizes and has a good price/performance ratio.

Application examples

  • Spectrometer calibration
  • Densitometer calibration for reflective measurements
  • Camera white balancing
  • Exposure checking
