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. WebThin lens approximation. For a thin lens in air, the focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens.For a converging lens (for example a convex lens), the focal length is positive and is the distance at which a beam of collimated light will be focused to a single spot. For a diverging lens (for example a … resort world cigar lounge
