Refrigerated fiber optic spectrometer

Typical application areas:

Fluorescence/Raman spectroscopy fluorescence intensity is usually one order of magnitude weaker than excitation light, belonging to weak light signals. In order to detect fluorescence spectra, high-sensitivity fiber optic spectrometers are generally required; In contrast, Raman signals are even weaker and generally require fiber optic spectrometers with the ability to expose for long periods of time.

The difference in intensity between the target light and the reference light in the absorption spectrum can reach up to three orders of magnitude, which requires a signal-to-noise ratio of over 1000:1 for the fiber optic spectrometer.

Microscopic spectroscopy requires the collection of spectral signals in the micrometer scale region, which requires fiber optic spectrometers to have the ability to detect weak optical signals.

In the angular resolution spectroscopy system, the optical signal is decomposed into various angles and collected one by one, which requires the spectrometer to have the ability of weak light detection and high-speed acquisition.
