Measurement Methodology
Light transmitted via optical fiber reflects at the film's upper and lower surfaces, creating two phase-shifted beams. Their interference spectrum, recorded by the spectrometer, enables thickness calculation using the extremum method with θ, n, and peak/trough data. Thicker films increase fringe frequency, while longer wavelengths decrease it. Optimal measurement requires proper spectral range and resolution selection.
Typical Applications
- Absorption, transmittance and reflection spectrum detection
- Light source and laser wavelength characterization
- OEM product modules: Fluorescence spectrum, Raman spectrum, etc.
