Film Thickness Measurement Quantitation of Amount of Fat in Foods
Interference wave patterns sometimes occur when light passes Recently, fat-modified products have become widely available. The Gerber method and Roese-Gottlieb method are usually used
through a transparent film. The film thickness of a sample can be Options Used for Measurements to determine the fat level in milk, a process that requires a long measurement time. Therefore, the measurement was conducted
determined by using the interference waveform. The black line is for using a combination of the spectral reflectance method and multivariate analysis. The figure below shows the spectral reflectance

incident angle and wavelength range for the film
thickness calculation. The diffuse reflectance spectra of various textiles were measured in the
visible region using the ISR-603 integrating sphere attachment.
The blue line indicates a blue fabric and the red line indicates a red fabric.
The blue fabric mainly reflects short-wavelength blue light, so it appears
blue, while the red fabric mainly reflects long-wavelength red light, so it
appears red.
