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.

Euclid s Optics , is a work on the geometry of vision written by the Greek mathematician Euclid around 300 BC. The earliest surviving manuscript of Optics is in Greek and dates from the 10th century AD. The work deals almost entirely with the geometry of vision, with little reference to either the physical or psychological aspects of sight. No Western scientist had previously given such mathematical attention to vision. Euclid s Optics influenced the work of later Greek, Islamic, and Western European Renaissance scientists and artists. Historical significance See also History of optics Writers before Euclid had developed theories of vision.

Active optics is a technology for reflecting telescope s developed in the 1980s, which has more recently enabled the construction of a generation of telescopes with 8 metre primary mirrors. Active optics works by actively adjusting the telescope s mirror s. This method is used by, among others, the Nordic Optical Telescope , the New Technology Telescope , the Telescopio Nazionale Galileo and the Keck telescope s, as well as all of the largest telescopes built in the last decade. Most modern telescopes are reflectors, with the Primary mirror primary element being a very large mirror . Historically, the mirrors had to be very thick to hold its shape to the required accuracy as the telescope travelled across the sky. This limited their maximum diameter to 5 or 6 metre s 200 or 230 inch es , such as in the Palomar Observatory s Hale telescope . A new generation of telescopes built since the 1980s uses instead very thin mirrors, which are too thin to keep themselves rigidly in the correct shape.

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.

Image Loupe binoculaire p1030891.jpg thumb right Several objective lenses on a microscope. In an optics optical instrument, the objective is the optical element that gathers light from the object being observed and focuses the rayoptics light rays to produce a real image . Objectives can be single Lens optics lenses or mirror s, or combinations of several optical elements. They are used in microscope s, telescope s, camera s, slide projector s, CD player s and many other optical instruments. Objectives are also called object lenses , object glasses , or objective glasses . Types Microscope The objective lens of a microscope is the one at the bottom near the sample. At its simplest it is a very high powered magnifying glass , with very short focal length . This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube. The objective itself is usually a cylinder containing one or more lenses that are typically made of glass its function is to collect light from the sample. A typical microscope has several objective lenses with different focal lengths screwed into a circular nose piece which may be rotated to select the required lens. The lenses are typically designed to be Parfocal lens parfocal , which means that when one changes from one to another the sample stays in focus optics focus . Microscope objectives are characterized by two parameters magnification and numerical aperture . The former typically ranges from 4 to 100 , while the latter ranges from 0.10 to 1.25, corresponding to focal lengths of about 40 to 2  mm, respectively. For high magnification applications, an oil immersion objective or water immersion objective has to be used. The objective is specially designed and Index matching material refractive index matching oil or water must fill the air gap between the front element and the object to allow the numerical aperture to exceed 1, and hence give greater resolution at high ... more details
