WebPractically, in a confocal laser scanning microscope (CLSM), the focal point of a laser generated by a lens is scanned across a specimen to build up a two-dimensional (2D) optical section. Three-dimensional (3D) images can be reconstructed by capturing a series of 2D images at different focal depths in the specimen. WebThe focal length of a lens system is defined as the distance from the lens center to a point where parallel rays are focused on the optical axis (often termed the principal focal point ). An imaginary plane perpendicular to the principal focal point is …

WebA portion of the light reaching the objective emanates from the periphery of the specimen, and enters the optical system at oblique angles, advancing diagonally (but still in parallel bundles) toward the tube lens. All of the light gathered by the tube lens is then focused at the intermediate image plane, and subsequently enlarged by the eyepiece.

WebThe term confocal derives from the coincidence of these two focal planes (objective lens focus point and the focus point where the aperture is placed). The result is the removal of out-of-focus light, providing a crisp image with the maximal resolution possible for the objective lens being used. WebLenses can be either positive or negative depending upon whether they cause light rays passing through to converge into a single focal point, or diverge outward from the optical axis and into space. Positive lenses …
