In modern operations for cataract , the lens capsule is not removed and so months or years of operation the lens become opaque. So before the advent of laser surgery a tiny knife called cystitome was used to cut a hole in the center of lens capsule,thus providing a clear path for light rays to reach retina .This procedure thus reduces the opacity of the lens of the eye. Currently this procedure is replaced by YAG laser capsulotomy. So capsulotomy is used to reduce opacity of the lens after some cataract surgeries if opacity occurs after surgery . ref Oxford Concise Medical Dictionary, 2002. ref References Reflist Eye surgery Category Medicine Category Eye surgery ... more details

Orphan date February 2009 The source function is a characteristic of a stellar atmosphere, and in the case of no scattering of photons, describes the ratio of the emission coefficient to the absorption coefficient. It is a measure of how photons in a light beam are removed and replaced by new photons by the material it passes through. Its units in the cgs system are erg s sup 1 sup cm sup 3 sup sr sup 1 sup and in SI are W m sup 3 sup sr sup 1 sup . The source function can be written math S lambda stackrel mathrm def frac j lambda kappa lambda math where math j lambda math is the emission coefficient, math kappa lambda math is the absorption coefficient also known as the opacity optics opacity . Putting this into the equation for radiative transfer we get math frac 1 kappa lambda rho frac dI lambda ds I lambda S lambda math where s is the distance measured along the path traveled by the beam. The minus sign on the left hand side shows that the intensity decreases as the beam travels, due to the absorption of photons.

The folio is held at a distance of 15 cm. from a constant 60 watt light source such as an unshaded table lamp . A dowel or pencil is held behind and against it, creating a silhouette. Folios are added until the outline of the pencil is no longer visible.

The mechanism is the driving mechanism behind the changes in luminosity of many types of pulsating variable stars. Here, the Greek letter kappa is used to indicate the radiative opacity optics opacity at any particular depth of the stellar atmosphere. In a normal star, an increase in compression of the atmosphere causes an increase in temperature and density this produces a decrease in the opacity of the atmosphere, allowing heat energy to escape more rapidly. The result is an equilibrium condition where temperature and pressure are maintained in a balance. However, in cases where the opacity increases with temperature, the atmosphere becomes unstable against pulsations. ref name maeder2009 If a layer of a stellar atmosphere moves inward, it becomes denser and more opaque, causing heat flow to be checked. In return, this heat increase causes a build up of pressure that pushes the layer back out again. The result is a cyclic process as the layer repeatedly moves inward and then is forced back out again. ref name de boer seggewiss2008 Stellar non adiabatic pulsation resulting from the mechanism occurs in regions where hydrogen and helium are partly ionized, or where there are negative hydrogen ions. An example of such a zone is in RR Lyrae variable s where the partial second ionization of helium occurs. ref name maeder2009 Hydrogen ionization is most likely the cause of pulsation activity in Mira variable s, Ap and Bp star rotating Ap stars and Pulsating white dwarf ZZ Ceti variables . In Beta Cephei variable s, stellar pulsations occur at a depth where the temperature reaches approximately 200,000 K and there is an abundance of iron. The increase in the opacity of iron at this depth is known as the Z bump, where Z is the astronomical symbol for elements other than hydrogen and helium. ref name leblanc2010 References reflist refs ref name de boer seggewiss2008 cite book author de Boer, Klaas Sjoerds Seggewiss, Wilhelm title Stars and stellar evolution page ... more details

Unreferenced date October 2008 Opalescence is a type of dichroism seen in highly colloid dispersed systems with little Opacity optics opacity . The material appears yellowish red in transmitted light and blue in the scattered light perpendicular to the transmitted light. The phenomenon is named after the appearance of opal s. There are different degrees of opalescent behaviour. One can still see through a slightly opalescent phase. The more particles and the bigger the particles are, the stronger the scattering arising from them and the cloudier the particular phase will look. At a certain concentration the scattering is so strong that all light passing through is scattered, so that it is not transparent any more. Examples are the Diffuse sky radiation blue sky in the daytime and the yellowish red sky at sunset. Another example can be made by adding a few droplets of milk to a glass of water. The liquid appears bluish but if one looks through the glass at a light source, it becomes yellowish red. Opalescence is an effect exploited in lustreware pottery.
