Lense ea mahlo

Lense ea optical ke lense e entsoeng ka khalase ea optical.Tlhaloso ea khalase ea optical ke khalase e nang le thepa e tšoanang ea optical le litlhoko tse khethehileng bakeng sa thepa ea optical e kang refractive index, dispersion, transmittance, spectral transmittance le light absorption.Khalase e ka fetolang tsela ea ho hasana ea leseli le kabo ea spectral e lekanyelitsoeng ea lebone la ultraviolet, le bonahalang kapa la infrared.Ka kutloisiso e moqotetsane, khalase ea optical e bolela khalase ea optical e se nang mebala;Ka kutloisiso e pharaletseng, khalase ea optical e boetse e kenyelletsa khalase ea 'mala oa optical, khalase ea laser, khalase ea quartz optical glass, anti radiation glass, ultraviolet infrared optical glass, fiber optical glass, acoustooptic glass, magneto-optical glass le photochromic glass.Khalase ea optical e ka sebelisoa ho etsa lilense, liprism, liipone le lifensetere ka lisebelisoa tsa optical.Likarolo tse entsoeng ka khalase ea optical ke likarolo tsa bohlokoa tsa lisebelisoa tsa optical.

Khalase eo qalong e neng e sebelisoa ho etsa lilense ke makukuno a likhalaseng tse tloaelehileng tsa fensetere kapa libotlolong tsa veine.Sebopeho se tšoana le "moqhaka", moo lebitso la khalase ea moqhaka kapa khalase ea poleiti ea moqhaka le hlahang teng.Ka nako eo, khalase e ne e sa lekana ebile e foqoha.Ho phaella ho khalase ea moqhaka, ho na le mofuta o mong oa khalase ea lejoe le thata e nang le lintho tse ngata tse etellang pele.Hoo e ka bang ka 1790, Pierre Louis junnard, monna oa Mofora, o ile a fumana hore soso ea khalase e hlohlelletsang e ka etsa khalase e nang le sebopeho se tšoanang.Ka 1884, Ernst Abbe le Otto Schott ba Zeiss ba ile ba theha Schott glaswerke Ag Jena, Jeremane, 'me ba etsa likhalase tse ngata tsa mahlo ka mor'a lilemo tse seng kae.Har'a bona, ho qaptjoa ha khalase ea moqhaka oa barium e nang le index e phahameng ea refractive ke e 'ngoe ea katleho ea bohlokoa ea fektheri ea khalase ea Schott.

Khalase ea optical e kopantsoe le oxides ea silicon e hloekileng haholo, boron, sodium, potasiamo, zinki, lead, magnesium, calcium le barium ho ea ka foromo e khethehileng, e qhibilihisitsoeng ka mocheso o phahameng ka platinum crucible, e tsosoa ka mokhoa o ts'oanang le leqhubu la ultrasonic ho tlosa bubble. ;Ebe o pholile butle ka nako e telele ho qoba khatello ea kelello ka hare ho thibela khalase.Sebaka sa khalase se pholileng se tlameha ho lekanyetsoa ka lisebelisoa tsa optical ho hlahloba hore na bohloeki, pepenene, ho tšoana, index ea refractive le index ea dispersion li kopana le litlhaloso.Sebaka sa khalase se nang le tsebo sea futhumatsoa 'me se qhekelloa ho etsa "optical lens rough embryo".
