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.
Its fundamental purpose is to provide so-called optical sectioning and thus to enable the recording of three-dimensional images, which is impossible to achieve with conventional wide-field microscopy.

Many pages are copied from Internet web pages or from presentations given by Leica, Zeiss and other companies. You will need proven experience of working with advanced light microscopy systems e.g confocal, super-resolution, high content and multiphoton systems. You will need knowledge of physics, optics, biology to provide innovation solutions to meet customer application and scientific requirements. Re-scan Confocal Microscopy (RCM) is a new super-resolution technique, based on standard confocal microscopy. It’s extended with an optical re-scanning unit that projects the image directly on a CCD- or sCMOS camera.
Spinning disk confocal microscopy (c) illuminates the sample with a rotating pattern of 1,000's of pinholes for complete simultaneous confocal illumination.

Introductory Confocal Concepts. Confocal microscopy offers several advantages over conventional optical microscopy, including shallow depth of field, elimination of out-of-focus glare, and the ability to collect serial optical sections from thick specimens. In the biomedical sciences, a major application of confocal microscopy involves imaging Confocal Raman microscopy can be used to determine layers in a multi-layer sample. Firstly, a cross-section of a sample can be made and the sample mapped across the sections (Figure 9).

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). 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. The general demands placed upon the objective in the confocal instrument are similar to those in other critical microscopy applications, although the ever-expanding requirements imposed by new techniques have made it more common than ever to approach the performance limits of these lens systems.
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.

The Most Versatile Microscope for Life Sciences - Life Science
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]. 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 based on the principle of the scanning optical microscope. In the most widely used and simple form of the instrument, laser light is focused by an objective lens ( Fig. 21.1 ) on to the object, and the reflected, or fluorescent, light focused on to a photodetector via a beamsplitter. Confocal microscopy offers several advantages over conventional optical microscopy, including shallow depth of field, elimination of out-of-focus glare, and the ability to collect serial optical sections from thick specimens. In geometry, confocal means having the same foci: confocal conic sections.
