What are the classification of fiber optic spectrometers?
1 Emission Spectrum ● Principle: When a substance is excited by external factors such as heat, electricity, light, or magnetism, its internal atoms or molecules transition to higher energy levels and then return to lower energy levels, releasing photons to form a spectru...Read more -
How is SNR calculated?
The signal-to-noise ratio (SNR) of a spectrometer is a crucial performance indicator that reflects the relative relationship between the spectral signal and background noise. A higher SNR indicates less noise interference with the signal, resulting in higher quality spec...Read more -
