For even more individual purposes we also offer restan in different sized plates. Individual calibration is available on request.
Restan
Our PTFE (Polytetrafluoroethylene) 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.
