Muraayadaha Layard (aka Nimrud Lens)

Lanshanka ugu caansan ee la ogaaday, illaa hadda, waa Layard Lens (aka: "Nimrud Lens"); waxaa laga helay by AH Layard ee 1853 oo ku dhowaad 3000 sano jir ah (ku saabsan 750BC-710BC ee Boqortooyada Neo-Assyrian).

Waqtigan xaadirka ah, waxay ku taal bandhigga Maktabiga Britishka; kormeeraha ma aha mid aad u hubsan oo ku saabsan qiimeynta Laanahiisa ee wax soo saarista, si kastaba ha ahaatee, waxayna u maleyneysaa inay ujeedkeedu yahay in lagu qurxiyo. Si ula kac ah ama aan ahayn, si kastaba ha ahaatee, waa is muraayad, inkastoo ay tahay mid aan caadi aheyn.

Waxyaabaha ugu weyn ee iftiinka ah ee dhacay waxay ahayd horumar ah aragtida casriga casriga ah; aqoonyahanno badan, dhakhaatiir, physicists, inventors, iyo xisaabiyayaashu waxay ku lug lahaayeen tijaabooyinka iyo fikradaha. Inta badan, Thomas Young (England) & AJ Fresnel (Faransiiska), horumarinta aragtida mugdiga ee iftiinka. James Clerk Maxwell (Scottish), oo leh aragtida elektromagnetic ee iftiinka 1864, isaga oo raacay shaqada uu ku sawiray sawirada midabka hore ee isku midka ah (wareega 1860). Max Planck (Jarmalka) iyo isaga galmada aragtida 1900 ka caawisay sharaxaadda iftiinka; Albert Einstein (ugu dambeyntii United States) ee 1905 sii kordhiyay sharraxaadda Planck ee iftiinka, noo keeno Photon.

Horumarinta gudaha galmada makaaniku waxay sharxeen wax badan oo ku saabsan iftiinka 1935.

Iyadoo dhammaan dadka aadka u iftiimaya ee ka shaqeeya aragti iftiin ah, waa muhiim in aan lumin aragtida maskaxaha kale ee tooska ah ee tooska u shaqeeya lenses. Carl Friedrich Gauss, oo ah Jarmal Mathematical Jarmal, ayaa si weyn uga faa'iidaystay muraayadaha casriga ah, iyo fahamka isticmaalka. Isaga Dioptrische Untersuchungen Wax badan ayaa ina baray, oo ay ku jiraan falanqaynta fistiga ee muuqaalka muuqaalka leh ee Gaussian Optics.

Sanadihii xigay ee 100, ugu yaraan shaqadiisa ayaa gacan ka geysatay hagidda farsamooyinka farsamada wax ku oolka ah, gaar ahaan sharaxaadda shan shey oo waaweyn oo muraayado ah (astigmatism, miyir-beel, jahwareer, curyaaminta beerta Petzval, iyo guud ahaan).

Inkasta oo shuruudahaas loo isticmaalay indhaha indhaha, waxaa loo adeegsadaa muraayadaha indhaha, hubaalna wax kasta oo u baahan muraayad ka timaada sawirada sawirada illaa muraayadaha indhaha - taas oo nagu keenta muraayadaha loo isticmaalo maanta sawirro fiidiyoow ah oo ay isticmaalaan xarumaha warbaahinta iyo xirfadlayaasha kale ee goobta ku yaal.
