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
