Accurate Film Thickness Measurement with F/4 Cross-Type Optical Design Fiber Optic Spectrometer

Critical to semiconductors, PV panels, and display tech, thin films require meticulous thickness monitoring. Photoelectric techniques revolutionize this process through harmless, high-speed measurements. Modern systems combine optical instruments with AI algorithms to optimize film production, ensuring superior quality while accelerating industrial advancement.

• 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

When light from the optical fiber probe strikes the film, dual reflections occur: one at the air-film surface and another at the film-substrate interface. The resulting beams interfere, producing spectral fringes detected by the spectrometer. The optical path difference enables thickness (d) determination using the extremum method, with inputs including θ, n, and spectral peaks. Thicker films exhibit tighter fringe spacing, whereas longer wavelengths spread them out. Measurement accuracy depends on appropriate wavelength and resolution settings.
