I-galvanometer yi-galvanometer ye-galvanometer esetyenziswe kwishishini lase-laser. Igama layo lobugcisa yinkqubo ehamba ngesantya esiphezulu se-Gavanometer.Ukusebenza okusebenzayo, ukuchaneka kwendawo ephezulu, isantya esiphezulu sokumakisha, ubuchule obuqinileyo bokulwa, kunye neempawu zentsebenzo zomsebenzi eziqinisekileyo fikelela kwinqanaba lobugcisa lohlobo olufanayo lweemveliso ekhaya kunye nasephesheya. I-galvanometer yeskena inokulayishwa nge-10mm ye-10mm ye-10mm ye-suctule, kunye neyona ndawo iphezulu ye-factula yendalo yi-10mm. Isetyenziselwa ukuskenwa kweskeni, ukumakisha i-laser, ukuqhuba, ukusebenzisana kunye neshishini lonyango. Inkqubo yeskena yeskena ineempawu zesantya esiphezulu, i-drift ephantsi, ukuchaneka okuphezulu kunye nokuzinza okuthembekileyo kunye nokuzinza.
