This technique is used extensively in the scientific and in Confocal microscopy is a specialized form of standard fluorescence microscopy (also called widefield fluorescence microscopy) that uses particular optical components to generate high-resolution images of material stained with fluorescent probes. There were many attempts in the later half of the twentieth century to achieve improved image resolution for fluorescence microscopy by use of various apertures, however the availability of high intensity lasers and sensitive electronic detectors Confocal microscopy provides only a marginal improvement in both axial (z; along the optical axis) and lateral (x and y; in the specimen plane) optical resolution, but is able to exclude secondary fluorescence in areas removed from the focal plane from resulting images. Even though resolution is somewhat enhanced with confocal microscopy over conventional widefield techniques, it is still considerably less than that of the transmission electron microscope. Our confocal microscope (from Noran) uses a special Acoustic Optical Deflector in place of one of the mirrors, in order to speed up the scanning. This uses a high-frequency sound wave in a special crystal to create a diffraction grating, which deflects the laser light (actually, the first diffraction peak is used, with the zeroth-order peak being thrown away). Confocal microscopy is broadly used to resolve the detailed structure of specific objects within the cell. Similar to widefield fluorescence microscopy, various components of living and fixed cells or tissue sections can be specifically labeled using immunofluorescence, for example, and then visualized in high resolution.

The confocal microscope is a specific fluorescent microscope that allows obtaining 3D images of the sample with good resolution. In these microscopies, the sample contains fluorescent molecules. These molecules are excited by a light beam and their fluorescence is then detected. In Confocal Microscopy Methods and Protocols, Stephen Paddock and a highly skilled panel of experts lead the researcher using confocal techniques from the bench top, through the imaging process, to the journal page. They concisely describe all the key stages of confocal imaging-from tissue 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.

For any conventional optical microscope configuration, the objective is the most critical component of the system in determining the information content of the image. The contrast and resolution of fine specimen detail, the depth within the specimen from which information can be obtained, and the lateral extent of About Confocal Confocal Laser Scanning Microscopy (CLSM) is one of a series of methods to generate slices from microscopic samples by means of optics. The sample stays intact, and the slicing may be repeated many times. True Confocal Scanning (TCS) is a technique, where only a single, diffraction limited spot is illuminated and observed at a time.

Microscope - Microscope - Confocal microscopes: The field of view of a microscope is limited by the geometric optics and by the ability to design optics that provide a constant aberration correction over a large field of view. If a scanning arrangement is used, the objective can be used over a continuous series of small fields and the results used to build up an image of a larger region.

Konfokalmikroskopi Svensk MeSH

Similar to widefield fluorescence microscopy, various components of living and fixed cells or tissue sections can be specifically labeled using immunofluorescence, for example, and then visualized in high resolution. Confocal microscopy is a powerful technique to image fluorescent samples given its high efficiency, low background noise and the capability to optically section samples into different focal planes. Example of a confocal microscopy micrograph.

Confocal microscopy offers several advantages over conventional widefield optical microscopy, including the ability to control depth of field, elimination or reduction of background information away from the focal plane (that leads to image degradation), and the capability to collect serial optical sections from thick specimens.
