Confocal Laser Scanning Microscope Images

Relatively thick specimens can be imaged in successive volumes by acquiring a series of sections along the optical z axis of the microscope.

Confocal laser scanning microscope images.

The key feature of confocal microscopy is its ability to produce. In the non confocal image specimen planes outside the focal plane degrade the information of interest from the focal plane and differently stained specimen details appear in mixed color. This means that we can view visual sections of tiny structures that. In the confocal.

Confocal microscopy offers several advantages over conventional optical microscopy including controllable depth of field the elimination of image degrading out of focus information and the ability to collect serial optical sections from thick specimens. The confocal also includes a very large box containing electronics which is not shown in the photographs. The confocal microscope attachment shown in these pictures contains the optics for scanning the laser beam and the pinhole. Laser scanning confocal microscopy.

Clsm combines high resolution optical imaging with depth selectivity which allows us to do optical sectioning. A thick section of fluorescently stained human medulla in widefield fluorescence exhibits a large amount of glare from fluorescent structures above and below the focal plane figure 1 a. For reference purposes the confocal system should have a digital file of an image of the test specimen accessible to users of the microscope including all parameters of its collection such as laser power pinhole diameter objective lens and zoom value and gain and black level of the detector. There is also a laser and an sgi computer.

With confocal laser scanning microscopy clsm we can find out even more. Laser scanning confocal microscopes employ a pair of pinhole apertures to limit the specimen focal plane to a confined volume approximately a micron in size. Confocal microscopy most frequently confocal laser scanning microscopy clsm or laser confocal scanning microscopy lcsm is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out of focus light in image formation.

Presented in figure 1 are a series of images that compare selected viewfields in traditional widefield and laser scanning confocal fluorescence microscopy. Fluorescent microscopy not only makes our images look good it also allows us to gain a better understanding of cells structures and tissue. The confocal laser scanning microscope clsm is a microscope which focuses only on a single focal plane and the unfocused plane will not be visualized.
