1 SYSTEM OVERVIEW
Olympus FLUOVIEW FV500 is a confocal scanning type laser reflected fluorescence microscope which uses
confocal optics for high resolution, high contrast and drastically improved resolution in the light axis direction.
It offers researchers features for sectioning, 3D construction and time-series observation as well as a variety of
image processing and analysis functions.
This section describes the principle and characteristics of the system and the functional configuration of
software for use with the system.
1-1 Principle
A laser scanning microscope converges a laser beam into a very small spot using an
objective and scans the specimen in the X-Y directions.
It then detects the fluorescence and transmitted light from the specimen using light
detector and outputs the image of the
specimen on an image monitor.
The confocal optics place a confocal
aperture at a position which is optically
conjugate with the focusing position (i.e.
confocal plane) to eliminate light from
parts other than those for the focusing
position. As a result, the part
corresponding to the eliminated light is
darkened in the image, making it
possible to slice a thick tissue
specimen optically.
On the other hand, with ordinary optical
microscopes, light from a part other
than the focusing position overlaps with
the image-forming light on the focusing
position, so the overall image tends to
be vague.
Transmitted light images can be
obtained by use of a transmitted light
detector, but the images will not be
confocal images, because there is no
confocal aperture in front of the detector.
The transmitted light image can be used by combination with a confocal fluorescence
image to observe fluorescent localization.
