O le Medical zoom/focus coupler ose masini e fa'aogaina ile vaega o vaila'au mo le fa'aleleia atili ole va'aiga ile taimi ole fa'afoma'i, aemaise ile endoscopy ma microscopy. Ua mamanuina e faʻafesoʻotaʻi i le va o le faʻataʻitaʻiga faʻafomaʻi faʻafomaʻi ma le meafaigaluega faʻapitoa, e pei o le endoscope poʻo le microscope, faʻatagaina le faʻaogaina ma le taulaʻi gafatia.O le mea faʻapipiʻi e mafai ai ona fesuiaʻi tulaga faʻalauteleina, faʻatagaina fomaʻi faʻapitoa e fetuunai le maualuga o le zoom e vaʻavaʻai totoʻa ma auʻiliʻili le vaega faʻatatau. E mafai ai foi ona sa'o le taula'i, fa'amautinoaina le lelei atoatoa o ata ma le manino i le taimi o le fa'agasologa. O le masini e masani lava ona faʻapipiʻiina mataʻitusi maualuga, faʻamautinoa le faʻaogaina o ata e leai se faʻalavelave ma le maualuga. Faatasi ai ma lona faʻaogaina o le soʻo ma le taulaʻi gafatia, e faʻaleleia ai le saʻo ma le lelei o togafitiga faafomaʻi, maua ai taunuuga sili atu mo gasegase.
