Muraayadda dahaarka leh waa dusha sare ee galaaska oo leh hal ama in ka badan lakab oo bir ah, oksaydh bir ah ama walxo kale, ama ayoonno bir ah oo guuray. Dahaarka galaaska wuxuu beddelaa milicsiga, tusmada refractive, nuugista iyo sifooyinka kale ee dusha sare ee galaaska una beddelaa hirarka iftiinka iyo elektromagnetic-ka, wuxuuna siiyaa dusha galaaska sifooyin gaar ah. Tiknoolajiyadda wax soo saarka ee galaaska dahaarka leh ayaa sii kordheysa, noocyada badeecadaha iyo shaqooyinka ayaa sii kordhaya, baaxadda codsiguna way sii ballaaranaysaa.
Kala soocidda galaaska dahaarka leh waxaa loo kala saari karaa iyadoo loo eegayo habka wax soo saarka ama shaqada isticmaalka. Sida waafaqsan habka wax soo saarka, waxaa jira galaas dahaar leh oo online ah iyo galaas dahaar leh oo online ah. Muraayadda dahaarka leh ee online-ka ah waxaa lagu dahaadhaa dusha sare ee galaaska inta lagu jiro habka sameynta galaaska sabeynaya. Marka la eego dhinaca kale, galaaska dahaarka leh ee offline-ka ah waxaa lagu farsameeyaa meel ka baxsan khadka wax soo saarka galaaska. Muraayadda online-ka ah waxaa ka mid ah sabeynta korontada, kaydinta uumiga kiimikada iyo buufinta kulaylka, dahaarka offline-ka ahna waxaa ka mid ah uumi-baxa faakuumka, buufinta faakuumka, sol-gel iyo habab kale.
Sida laga soo xigtay shaqada isticmaalka ee galaaska dahaarka leh, waxaa loo qaybin karaa galaas dahaarka leh oo xakamaynta iftiinka qorraxda,galaas-e hooseeya, galaaska filimka gudbiya, galaas is-nadiifinaya,galaas ka-hortagga milicsiga, muraayad muraayad ah, muraayad dhalaalaysa, iwm.
Marka la soo koobo, sababo kala duwan awgood, oo ay ku jiraan shuruudaha sifooyinka gaarka ah ee indhaha iyo korontada, ilaalinta agabka, dabacsanaanta naqshadeynta injineernimada, iwm., dahaarka ayaa la rabaa ama lagama maarmaan ah. Hoos u dhigista tayada ayaa aad muhiim ugu ah warshadaha baabuurta, sidaa darteed qaybaha birta culus (sida shabakadaha) waxaa lagu beddelaa qaybo balaastig ah oo khafiif ah oo lagu dahaadhay chromium, aluminium iyo biraha kale ama birta kale. Codsi kale oo cusub ayaa ah in lagu dahaadho filimka indium tin oxide ama filimka dhoobada birta gaarka ah daaqadda galaaska ama bir balaastikada ah si loo hagaajiyo waxqabadka badbaadinta tamartadhismayaasha.
Saida Glasssi joogto ah ayay ugu dadaalaysaa inay noqoto lammaanahaaga la isku halleyn karo oo ay kuu ogolaato inaad dareento adeegyada qiimaha lagu daray.
