cameras are even faster and take as little as 200 ns to transfer a frame. Each of
the foregoing characteristics should be considered in making a final choice of the
detector to be used for imaging and specifically for spectral imaging.
13.2.3 Multispectral Microscopy
Multispectral microscopy has generally been explored in the context of fluores-
cence or brightfield microscopy. In either mode of microscopy there are
a number of options that result in the ability to acquire spectral data sets,
each having its own set of advantages and disadvantages. Traditional use of
multispectral imaging has been coupled to fluorescence microscopy and, in turn,
based on multiposition filter wheels. Other methods include tunable illumi-
nation (as with monochromators),
