Optical axis 意味
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens, microscope or telescopic sight. The optical axis is an imaginary line that defines the path along which light propagates through the system, up to first approximation. For a system composed of simple lenses and mirrors, the axis passes through the center of c… WebA concave lens is a lens with a curved surface that is thickest along the edges and thinnest at the middle of the lens. We can create this shape by taking a cylinder and orienting its circular faces along the horizontal axis. If we then draw two spheres along the side of the cylinder, like we’ve shown here, and remove the overlapped material ...
