Lens-ku waa qalab iftiin caadi ah, muraayada caadiga ah ee caadiga ah waa lens-ka koonka ah, inta badan muraayadahani waxay ku tiirsan yihiin muraayadaha TIR.
Waa maxay muraayadda TIR?
TIR waxaa loola jeedaa "Guud- Milicsiga Gudaha", taas oo ah, wadarta milicsiga gudaha, oo sidoo kale loo yaqaan wadarta milicsiga, waa ifafaale indhaha ah.Marka iftiinku ka soo galo meel dhexe oo leh index refractive sare ilaa dhexdhexaad leh index refractive hoose, haddii xagal shilku ka weyn yahay xagal muhiim ah oo gaar ah θc (iftiinku waa ka fog yahay kan caadiga ah), iftiinka dib u iftiimaya wuu baaba'ayaa, iyo Dhammaan iftiinka shilka ayaa soo muuqan doona oo ha gelin meel dhexe oo leh index refractive hoose.
muraayada TIRwaxaa lagu sameeyaa iyadoo la adeegsanayo mabda'a guud ahaan milicsiga si loo ururiyo loona habeeyo iftiinka.Naqshaddeedu waa in ay isticmaasho iftiinka hore ee gasha, oo dusha sare ee duuban ayaa ururin karta oo ka tarjumaysa dhammaan iftiinka dhinaca, iyo isku dhafka labadan nuuc ee iftiinka ayaa heli kara naqshad iftiin ah.
Waxtarka lenska TIR wuxuu gaari karaa in ka badan 90%, wuxuuna leeyahay faa'iidooyinka heerka isticmaalka sare ee tamarta iftiinka, lumista iftiinka yar, meel yar oo iftiin ururin ah iyo isku mid ahaanshaha wanaagsan.
Waxyaabaha ugu muhiimsan ee lenska TIR waa PMMA (acrylic), kaas oo leh caag wanaagsan iyo gudbin iftiin sare (ilaa 93%).
