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
