WebA cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to intersection of the surface of the lens and a plane tangent to it along the cylinder's axis. WebThe constantA may be solvedbyconsidering the total power produced inthe reactor. This is obtained by multiplying the macroscopic fission cross section by the neutron flux, integrating overthe whole reactor and applying a conversion factor for the amount ofenergy producedinfission.
