Fast and Accurate Film Thickness Measurement Advanced Fiber Optic Spectrometer with 83% Quantum Efficiency at 232nm

With applications spanning electronics, renewables, and optics, thin film technology relies heavily on precise thickness evaluation for surface analysis. Photoelectric measurement solutions stand out for being contact-free, damage-proof, and fast. The integration of intelligent computing with optical systems enhances film quality control, supporting manufacturing upgrades and technological progress.

Note: The*are primarily designed for Raman applications, with the corresponding Raman.

• High quantum efficiency, 92%peak@650nm, 83%@232nm
• High SNR: Ultra-low dark noise under long integration time, SNR is as high as 1000:1
• Noise-free clear processing of weak signal in long exposure, strong adaption to environment
• Low-noise and high-speed circuit: USB3.0

A fiber-optic probe directs light toward the film, where it partially reflects at the air-film interface (first beam) and transmits through, reflecting again at the film-substrate boundary (second beam). These two beams interfere due to their path difference, generating an interference spectrum captured by the spectrometer. Thickness (d) is calculated via the extremum method using θ, n, and spectral extrema. Higher thickness increases fringe density, while longer wavelengths reduce it. Proper spectral range and resolution selection are critical for precision.

• Detect absorption, transmittance and reflection Spectrum
• Light source and laser wavelength characterization
• OEM product module: Fluorescence spectrum, Raman spectrum, etc.
