Emincane kakhulu funa makronapolniteli, kuyizinhlayiyana osayizi okuyizinto micrometer-30. Ziyakwazi nzima ngokwanele apholishiwe efanayo angabacwasi ngokushesha ngesikhathi ukusebenza ukulahlekelwa umbala waso bukhanye.

Mininapolniteli nge ubukhulu kuyizinhlayiyana 1.5 microns asetshenziswa kakhulu njalo. Lokhu kungenxa yokuthi amandla elinama enjalo siphakeme ngokwanele ukuze babhekane ngokuphumelelayo isilinganiso umthwalo umfutho ku nut.
