Ilensi iyisisetshenziswa esivamile sokukhanya, ilensi evamile yakudala kakhulu ilensi eyindilinga, futhi iningi lalawa malensi lincike kumalensi e-TIR.
Iyini i-TIR Lens?
I-TIR ibhekisela "Ekuboneni Kwangaphakathi Okuphelele", okungukuthi, ukuboniswa okuphelele kwangaphakathi, okubuye kwaziwe ngokuthi i-total reflection, kuyinto yokubona. Lapho ukukhanya kungena kusuka endaweni enenkomba ephakeme ye-refractive kuya endaweni enenkomba ephansi ye-refractive, uma i-engeli yesigameko inkulu kune-engeli ethile ebalulekile θc (ukukhanya kukude nokujwayelekile), ukukhanya okuhlanjululwe kuzonyamalala, futhi konke ukukhanya kwesigameko kuzovezwa futhi Ungangeni phakathi nendawo enenkomba ephansi ye-refractive.
Ilensi ye-TIRkwenziwa ngokusebenzisa isimiso sokubonisa ngokuphelele ukuqoqa nokucubungula ukukhanya. Idizayini yayo iwukusebenzisa ukukhanya okugqobhozayo ngaphambili, futhi indawo ecijile ingaqoqa futhi ibonise konke ukukhanya okusemaceleni, futhi ukugqagqana kwalezi zinhlobo ezimbili zokukhanya kungathola iphethini yokukhanya ephelele.
Ukusebenza kahle kwelensi ye-TIR kungafinyelela ngaphezu kuka-90%, futhi kunezinzuzo zezinga eliphezulu lokusetshenziswa kwamandla okukhanya, ukulahlekelwa ukukhanya okuncane, indawo encane yokuqoqa ukukhanya nokufana okuhle.
Izinto eziyinhloko ze-TIR lens yi-PMMA (i-acrylic), ene-plasticity enhle kanye nokudlulisa ukukhanya okuphezulu (kufika ku-93%).
