I-zoom / i-coupler yezokwelapha / i-coupler yezokwelapha iyithuluzi elisetshenziswa emkhakheni wezokwelapha ukuze uthuthukise ukubona ngeso ngesikhathi sezinqubo zezokwelapha, ikakhulukazi e-Endoscopy kanye naseMicroscopy. Yenzelwe ukuxhumana phakathi kohlelo lokucabanga lwezokwelapha kanye nethuluzi le-optical, njenge-endoscope noma i-microscope, ukunika amandla ukusondeza kanye nokugxilisa amakhono wokukhulisa, ukuvumela ochwepheshe bezokwelapha ukuguqula indawo yokusondeza eduze futhi bahlaziye indawo okuhlosiwe. Iphinde inike amandla ukugxila okuqondile, iqinisekisa ikhwalithi ephezulu yesithombe nokucaca ngesikhathi senqubo. Idivaysi imvamisa ifaka ama-Optics asezingeni eliphakeme, iqinisekisa ukwahlukana kokuhlanekezelwa futhi okuphezulu kokucabanga okuphezulu.Ukusondeza i-coupler kuyithuluzi elibalulekile ezilungiselelweni zezokwelapha, njengoba kusiza ekuhlolweni kahle kwabasebenzi bezokwelapha. Ngokusondeza kwayo ukuguquguquka nokugxila kokugxila, kuthuthukisa ukunemba kanye nokusebenza kahle kwezinqubo zezokwelapha, ukuhlinzeka ngemiphumela engcono yeziguli.
