Measure coating thickness and characteristics in less than 2 minutes

With the OSeeT technology from Phyllon the measurement of tablet coating quality including

  • Coating thickness
  • Coating homogeneity
  • Surface roughness

can easily be measure at-line as shown in the Video below. The system works as an In-line application but also at line.

 

The Technology behind OSeeT is Interferometry

  • OCT is based on white light interferometry:
    – broad bandwidth resulting in low-coherence length
    – defines the axial (=depth) resolution
  • Light is split into a reference and a probe path
  • Optics of sample arm focus light and define lateral (=surface) resolution
  • Interference of light reflected back from both paths
  • Spectrometer (grating, CCD line scan camera)
  • Depth-information is generated from interference fringes by Fourier-transformation (FFT)
  • Measurement of a single depth scan
