Laser Scanning Confocal Microscopy(LSCM, also referred to as CSLM, Confocal Scanning Laser Microscopy) is now established as a valuable tool for obtaining high resolution images and 3-D reconstructions of a variety of biological specimens. In LSCM, a laser light beam is expanded to make optimal use of the optics in the objective. Through a x-y deflection mechanism this beam is turned into a scanning beam, focussed to a small spot by an objective lens onto a fluorescent specimen. The mixture of reflected light and emitted fluorescent light is captured by the same objective and(after conversion into a static beam by the x-y scanner device) is focused onto a photodetector(photomultiplier) via a dichroic mirror(beam splitter). The reflected light is deviated by the dichroic mirror while the emitted fluorescent light passes through in the direction of the photomultiplier. A confocal aperture(pinhole) is placed in front of the photodetector, such that the fluorescent light(not the reflected light!) from points on the specimen that are not within the focal plane(the so called out-of-focus light) where the laser beam was focussed will be largly obstructed by the pinhole. In this way, out-of-focus information(both above and below the focal plane) is greatly reduced. 2, record 1, English, - confocal%20laser%20scanning%20microscopy

Principe de la microscopie confocale à balayage laser (MCBL). Le rayon laser excitateur pénètre dans l'échantillon préalablement marqué par des fluorochromes [...], auparavant répertoriés et choisis en fonction de leurs propriétés à se fixer sur des molécules particulières d'une structure ou d'un objet d'intérêt. Lors de l'impact optique, il y a émission de rayons lumineux provenant de différents plans de la préparation. Grâce à un diaphragme variable («trou d'aiguille» - pinhole), il est possible de sélectionner les rayons émis par un seul plan de préparation et d'éliminer le signal provenant d'autres plans. Les rayons réfléchis sont filtrés en fonction de leur longueurs d'onde puis détectés par des photo-multiplicateurs. Le signal reçu est enfin converti en signal numérique, contribuant à la création d'une image [...] 2, record 1, French, - microscopie%20confocale%20%C3%A0%20balayage%20laser

Le microscope confocal à balayage laser (MCBL) est un microscope optique à éclairage épiscopique géré par un ordinateur qui est capable de sectionner optiquement un échantillon épais. Son image est ensuite reconstruite en superposant toutes ou certaines des sections optiques. Le faisceau lumineux (laser) balaie la surface de l'échantillon au moyen d'un miroir galvanométrique et la lumière réfléchie ou émise (fluorescence) provenant de chaque point de la surface balayée est recueillie par un détecteur, numérisée et stockée dans la mémoire de l'ordinateur. Sur le trajet des rayons provenant de l'échantillon se trouve un diaphragme (pinhole), situé sur l'avant du détecteur dans le plan conjugué avec celui de l'échantillon (confocal). Seuls les rayons image venant du plan focal, qui est confocal avec le plan du diaphragme, parviennent au détecteur. Les autres rayons, provenant d'autres plans focaux, sont bloqués par le diaphragme [...]. L'image résultante obtenue par balayage au niveau du plan focal a une épaisseur extrêmement limitée (section optique) et n'est pas perturbée par des images floues des plans situés au dessus ou au dessous. Comme l'ordinateur déplace la platine dans la direction de l'axe optique Z avec des mouvements micrométriques prédéfinis après chaque balayage, le MCBL ne peut pas recueillir les images provenant d'autres plans. L'ordinateur stocke les images correspondants aux sections optiques successives. Ces images peuvent être traitées de multiples manières. 3, record 2, French, - microscope%20confocal%20%C3%A0%20balayage%20laser

Specimens to be imaged with a CSLM [confocal scanning laser microscope] must be labelled with a fluorescent probe. Fluorescent probes are available for a wide range of biological preparations permitting the use of the CSLM to image such things as macromolecular structures(such as proteins, lipids, carbohydrates and nucleic acids) and physiological ions(such as Calcium and pH). The CSLM can be to image static fluorescent specimens, or to provide dynamic quantitative imaging and measurements. 1, record 3, English, - fluorescent%20probe
