Key Technical Characteristics
- High quantum efficiency: 92% peak @650nm, 83% @232nm
- High SNR: Ultra-low dark noise under long integration time (1000:1 SNR)
- Noise-free processing of weak signals in long exposure with strong environmental adaptation
- Low-noise, high-speed circuit with USB3.0 interface
Measurement Methodology
The system employs a fiber-optic probe to illuminate the film, generating reflections at both the air-film and film-substrate interfaces. These beams interfere to form a spectrum analyzed by the spectrometer. Using the extremum method—factoring in θ, n, and spectral extrema—film thickness (d) is computed. Fringe density correlates with thickness, while wavelength inversely affects it. Careful spectral range and resolution adjustments ensure reliable results.
Typical Applications
- Absorption, transmittance and reflection spectrum analysis
- Light source and laser wavelength characterization
- OEM modules for fluorescence and Raman spectroscopy
