Confocal Microscopy

چکیده
A confocal microscope creates sharp images of a specimen that would otherwise appear blurred when viewed with a conventional microscope. This is achieved by excluding most of the light from the specimen that is not from the microscope’s focal plane. The image has less haze and better contrast than that of a conventional microscope and represents a thin cross-section of the specimen. Thus, apart from allowing better observation of fine details it is possible to build three-dimensional (3D) reconstructions of a volume of the specimen by assembling a series of thin slices taken along the vertical axis.

The confocal microscope, based on the principle of confocal imaging, is a recently introduced and invaluable tool for high-resolution fluorescence microscopy. It has gained popularity in the scientific and industrial communities since its inception. Although the application of confocal microscopes in dentistry started as early as 1994, the practical usage of this device in our country is just g...
متن کامل[In vivo confocal microscopy in the diagnosis of fungal keratitis: case report].
The authors describe a case of fungal keratitis that the in vivo confocal microscopy helped in the diagnosis and follow-up. Confocal microscopy was done in a patient's ulcer that did not improve with several topical medicines. Corneal scrapings were obtained and culture results were without conclusion. We observed hyphae and infectious collections on confocal microscopy. New corneal culture sho...

AIMS To report the appearances of iridocorneal endothelial (ICE) syndrome from real time, white light confocal microscopy. METHODS Three consecutive patients, each with ICE syndrome, were examined prospectively. Corneal specular and confocal microscopic examinations were performed in all three patients. In the first patient, a penetrating keratoplasty was performed and the cornea was examined...
متن کاملOptical aberrations and objective choice in multicolor confocal microscopy.
Refinements in design have simplified confocal microscopy to the extent that it has become a standard research tool in cell biology. However, as confocal microscopes have become more powerful, they have also become more demanding of their optical components. In fact, optical aberrations that cause subtle defects in image quality in wide-field microscopy can have devastating effects in confocal ...
