Confocal microscopy is an optical imaging technique that uses spatial filtering (in most cases a pinhole), to block the out-of-focus light from physically reaching the sensor – in other words, optical sectioning. Although a confocal microscope will theoretically improve the lateral and axial resolution slightly compared to a widefield microscope.


In light microscopy, illuminating light is passed through the sample as uniformly as possible over the field of view. For thicker samples, where the objective lens

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.

The Confocal Microscope Core Facility administered by the Department of Neuroscience, Munroe-Meyer Institute at UNMC. This core provides state of the art digital imaging optical microscopes, quantitative software applications, and expert technical assistance. Confocal microscopy is nowadays one of the most extensively used tools for digital imaging. The advances in instrumental setup and fluorescence labelling strategies improve and broaden the possible experimental applications.

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

Confocal endomicroscopy 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.

Confocal Microscope Objectives. 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 Confocal Laser Scanning Microscopy (CLSM) is one of a series of methods to generate slices from microscopic samples by means of optics.

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).

The confocal microscope's ability to block out-of-focus light and thereby perform optical sectioning through a specimen allows the researcher to quantify fluorescence with very high spatial precision. However, generating meaningful data using confocal microscopy requires careful planning and a thorough understanding of the technique.

By using a sensitive camera as detector, the signal-to-noise ratio of the RCM is 4 times higher than in standard PMT-based confocal microscopes. Confocal microscopy enables the visualization and imaging of fixed as well as living cells and tissues that contain fluorescent probes (antibodies, green fluorescent proteins, dyes, substrates). This technique allows sharply defined optical sections to be collected, from which three dimensional rendering and movies can be created. Early confocal fluorescence images were published by Cox of the Oxford group in 1984 [47].
