Magalasi ndi zida zowunikira wamba, ma lens apamwamba kwambiri ndi ma conical, ndipo magalasi ambiri amadalira ma lens a TIR.
Kodi TIR Lens ndi chiyani?
TIR imatanthawuza "Total Internal Reflection", ndiko kuti, chiwonetsero chonse chamkati, chomwe chimadziwikanso kuti chiwonetsero chonse, ndizochitika zowoneka bwino.Kuwala kukalowa kuchokera ku sing'anga yokhala ndi cholozera chapamwamba cha refractive kupita ku sing'anga yokhala ndi cholozera chocheperako, ngati ngodya ya zochitikazo ndi yayikulu kuposa ngodya inayake yovuta θc (kuwala kuli kutali ndi kwanthawizonse), kuwala kowonekera kudzazimiririka, ndipo zowunikira zonse zidzawonetsedwa ndipo Osalowa sing'anga ndi index yotsika ya refractive.
TIR lensamapangidwa pogwiritsa ntchito mfundo ya kuwunikira kwathunthu kusonkhanitsa ndi kukonza kuwala.Mapangidwe ake ndi kugwiritsa ntchito kuwala kolowera kutsogolo, ndipo malo otsetsereka amatha kusonkhanitsa ndikuwonetsa kuwala konsekonse, ndipo kuphatikizana kwa mitundu iwiriyi ya kuwala kumatha kupeza mawonekedwe abwino kwambiri.
Kuchita bwino kwa lens ya TIR kumatha kufika kupitirira 90%, ndipo ili ndi ubwino wogwiritsa ntchito mphamvu zambiri zowunikira, kutayika kochepa kwa kuwala, malo ochepa osonkhanitsa kuwala ndi kufanana kwabwino.
Chinthu chachikulu cha lens ya TIR ndi PMMA (acrylic), yomwe ili ndi pulasitiki yabwino komanso kuwala kwapamwamba (mpaka 93%).
