Confocal Microscopic
Fluorescence
Experiment |
|
|
|
Excitation light is
focused by an
optical path from a
microscope objective
to small area of the
test substance,
stimulate
fluorescence, return
to microscope
optical path and
received by
spectrometer. The
spectroscopy
software shows the
testing substance
fluorescence
spectra, at the same
time, the laser
excited micro image
can be observed by
the camera
software... |
