The Oxford microscope was commercialised (the first commercial confocal microscope) by Oxford Optoelectronics, and later assigned to Lasersharp. Another important contributor to this era of the development of confocal microscopy was Brakenhoff [48]. 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.

Confocal microscopy

INTRODUCTION Confocal microscopy : (having the same focus ) An optical imaging technique for increasing optical resolution and contrast of a micrograph. Radiations emitted from laser cause sample to fluoresce. Uses pinhole screen to produce high resolution images. Eliminates out of focus. So images have better contrast and are less hazy. A series of thin slices of the specimen are assembled to Confocal Microscopy Confocal fluorescence microscopy is a technique used to acquire high-resolution optical sections within a thick sample or to reduce background fluorescence from a thin culture. Thorlabs manufactures complete confocal fluorescence systems, a confocal upgrade designed to interface with commercially available widefield microscopes, and components designed for custom Figure 1 Role of the confocal pinhole in a Raman microscope.

Capturing multiple two-dimensional images at different depths in a sample enables the reconstruction of three-dimensional structures within an object. 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.

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 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.

Laser scanning 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.
