Avantes has developed a bundle, especially for fluorescence measurements. This bundle is suited for various fluorescence applications.

When configuring a measurement setup for fluorescence applications, preventing excitation light from entering the spectrometer is an important issue. Possible methods to accomplish this, where one does not exclude the other, include:

Fluorescence spectroscopy, also known as fluorometry or spectrofluorometry, is a type of electromagnetic spectroscopy that analyzes a sample’s fluorescence. It involves using a beam of light that excites the electrons in molecules of certain compounds and causes them to emit visible light, typically, but not necessarily. It is a valuable technique in many biological (chlorophyll and carotenoid), biochemical (diagnosis of malignancies), and environmental applications.

Sep 3, 2021 — Meanwhile, lenses with short focal lengths have a larger depth of field, which enables them to get a wider range of elements in focus.

For most fluorescence applications, the amount of fluorescent energy emitted is only 3% of the amount of excitation light energy. Fluorescent light has a lower energy (higher wavelength) than excitation energy and is usually scattered light. This means it emits energy in all directions.

For optimal performance, assuming the time-acquisition window is not limited, Avantes recommends our Sensline spectrometers for this application since they can support long integration times, often exceeding 5 seconds. Avantes recommends the AvaSpec-ULS2048XL back-thinned CCD spectrometer when a higher-speed acquisition is required. For maximal sensitivity, the top model of the SensLine, our AvaSpec-HERO spectrometer, is recommended.

These are some of the products mentioned above. Contact one of our sales engineers for advice to find the perfect setup for your specific application.
