Fluorescence spectrum. The calculated values are based on theoretical calculations and may be different from the actual values when used on a flow cytometer. It is a form of luminescence. Fluorescence excitation and emission spectra are relatively broad due to the various energy states that exist in a molecule and optics are chosen so that a fluorophore is excited near its excitation maximum and then filtered to obtain signal near the emission maximum. Any filter configurations require user validation prior to use.

Fluorescence investigations are conducted with radiation having wavelengths ranging from the ultraviolet to the visible regions of the electromagnetic spectrum 250 to 700 nanometers.

In most cases the emitted light has a longer wavelength and therefore lower energy than the absorbed radiation. Fluorescence always takes place from the lowest vibrational level of the first excited state the shape of the emission spectrum is always the same despite changing the wavelength of exciting light.

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It involves using a beam of light usually ultraviolet light that excites the electrons in molecules of certain compounds and causes them to emit light. Biolegends fluorescence spectra analyzer is useful for the analysis of excitation and emission spectra of commonly used fluorochromes for flow cytometry. Fluorescence spectroscopy also known as fluorimetry or spectrofluorometry is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample.

Typically but not necessarily visible light.
