The OSeeT from Phyllon is based on Optical Coherence Tomography (OCT) research developed by The Research Center Pharmaceutical Engineering GmbH (RCPE). The focus of the OSeeT are enteric coatings (EC) and modified-release (MR) coatings.

The characteristics of the coating layer are revealed via OSeeT:

Mean coating thickness

→ progress of coating process

Intra-particle and inter-particle coating variability

→ for quality and homogeneity of the applied coating


→ optical quality of the surface

  • It is a fast and non-destructive system to evaluate the quality of film-coatings
  • An incredible level of detail
  • OSeeT provides direct measurement of the coating thickness
  • Through using OSeeT it is possible to closely monitor the performance of pan coaters
  • The 1D OSeeT probe is small
