The Beam Splitter gives you a flexible option for using dual light sources or spectrometers. The small size of the beam splitter allows it to directly mount to the front of any AvaSpec spectrometer or AvaLight Lightsource, eliminating the fibre interface. Another advantage is that your existing systems can be easily upgraded to a two- channel system. Being highly adaptable, the Beam Splitter enables easy measurement of two different applications at the same time (for example, a fluorescence and an absorption measurement).

The beam splitter/combiner can be used in several set-ups, combining several instruments. One possibility is to combine a fluorescence and an absorbance measurement.

By using the direct-attach beam combiner, we can measure absorbance and fluorescence at the same time. The beam combiner will receive both absorbance and fluorescence signals and can switch between these signals.
So we see both absorbance and fluorescence spectra in the software, the spectrum will only be updated when the beam combiner is in the right position.
