Unreferenced date December 2006 Image Vergence.svg thumb right Vergence of a beam. The vergence is inversely proportional to the distance from the focus in metres. If a positive lens is focussing the beam it has sit left of the focus, while a negative lens has to sit right of the focus to produce the appropriate vergence Otheruses Vergence disambiguation The vergence typical symbol L of a Ray optics light bundle in optics is the reciprocal of the distance between the focus optics point of focus and a reference plane. It is measured in dioptre s 1 D 1 m sup 1 sup . Vergence can also be understood as a measure of the curvature of the optical wavefront . However, it is only fully valid in geometrical optics , not in Gaussian beam optics or in wave optics where the wavefront at the focus is wavelength dependent and the curvature is not proportional to the distance from the focus. Convergence describes the situation when the light rays are approaching each other and its values are positive. Divergence is measured as negative dioptres and means that the beams are originating from a point.

For Gaussian beam optics Gaussian beam Gaussian optics is a technique in geometrical optics that describes the behaviour of light rays in optical systems by using the paraxial approximation , in which only rays which make small angles with the optical axis of the system are considered. ref A.Lipson, S.G.Lipson, H.Lipson, http books.google.it books?id aow3o0dhyjYC&pg PA51 v onepage&q&f false Optical Physics , IV edition, 2010, University Press, Cambridge, UK, p.51 ref In this approximation, trigonometric functions can be expressed as linear functions of the angles. Gaussian optics applies to systems in which all the optical surfaces are either flat or are portions of a sphere . In this case, simple explicit formulae can be given for parameters of an imaging system such as focal distance, magnification and brightness, in terms of the geometrical shapes and material properties of the constituent elements. Gaussian optics is named after Carl Friedrich Gauss , who showed that an optical system can be characterized by a series of Cardinalpointopticscardinal points , which allow one to calculate its optical properties. ref W.J.Smith, http books.google.it books?id DrtM bAnf YC&pg PA22 v onepage&q&f false Modern optical engineering the design of optical systems , McGraw Hill 2007, p.22 ref References reflist Category Geometrical opticsoptics stub ... more details

Electron optics deals with the focusing and deflection of electron s using magnetic field magnetic and or electrostatic field s. Electron properties main electron Electrons are charged particles point charges with rest mass . The electron also has an associated spin of 1 2. While in motion an electron possesses kinetic energy, regardless of any imposed charge field this could be achieved by accelerating electrons via a voltage differential into a screened field free region, which initially imparts the energy required to accelerate the electron. Given sufficient voltage the electron can be accelerated sufficiently fast to exhibit measurable relativistic effects, and the velocity must be accounted for relativistically. According to the wave particle duality , electrons can also be considered as wave propagations and therefore have associated wave properties such as wavelength, phase and amplitude. With respect to electron optics, the nature of the electron as a charged particle causes electrons to interact with imposed electron fields, and their spin causes magnetic field interactions as well. These interactions form the fundamentals of electron optical theory. Field interactions Particle interpretation Magnetic fields interact with an electron in a manner that alters velocity independently of kinetic energy velocity magnitude . Electrons move according to the cross product of the magnetic field and the electron propagation vector, such that, in an infinite uniform field moving electrons take a circular motion at a constant radius dependent upon electron velocity and field strength according to the following equation, which can be derived from circular motion math r frac 2 m cv eH math where r is the orbit radius, m is the mass of an electron, v is the electron velocity, e is the charge on the electron and H is the applied magnetic field. Electrons that have a velocity component ... Electron Optics Program DEFAULTSORT Electron Optics Category Electromagnetism de Elektronenoptik ... more details
