99zxc. Hoʻopili ʻana i nā ʻāpana ʻōpae plastik

I kēia manawa, ke hoʻomohala nei ka ʻoihana i nā uhi optical no nā noi e like me nā kāmela kikohoʻe, nā scanner bar code, nā sensor fiber optic a me nā pūnaewele kamaʻilio, a me nā ʻōnaehana palekana biometric. I ka ulu ʻana o ka mākeke ma ke ʻano o nā ʻāpana optical plastic haʻahaʻa ke kumu kūʻai, ua puka mai kekahi mau ʻenehana uhi hou e hoʻokō i nā pono o nā noi hou.

Ke hoʻohālikelike ʻia me nā optics aniani, ʻoi aku ka māmā o nā optics plastik i 2 a 5 mau manawa, e ʻoi aku ka kūpono no nā noi e like me nā mahiole ʻike pō, nā noi kiʻi lawe lima ma ke kahua, a me nā mea lapaʻau hiki ke hoʻohana hou ʻia a hoʻolei ʻia paha (e laʻa, laparoscopes). Eia kekahi, hiki ke hoʻoheheʻe ʻia nā optics plastik i nā pono hoʻonohonoho, no laila e hōʻemi nui ana i ka helu o nā ʻanuʻu hōʻuluʻulu a hoʻohaʻahaʻa i nā kumukūʻai hana.

Hiki ke hoʻohana ʻia nā optics plastik i ka hapa nui o nā noi kukui ʻike ʻia. No nā noi kokoke-UV a me kokoke-IR, ʻo nā mea maʻamau e like me ka acrylic (transparency maikaʻi loa), polycarbonate (ikaika hopena maikaʻi loa) a me nā olefins cyclic (ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa, ka omo wai haʻahaʻa) he pae nalu hoʻoili o 380 a 100 nm). Hoʻohui ʻia ka uhi ʻana i ka ʻili o nā ʻāpana optical plastik e hoʻomaikaʻi i kā lākou hana hoʻoili a i ʻole ka hoʻākāka ʻana a hoʻonui i ke kūpaʻa. ʻO nā uhi mānoanoa (ma kahi o 1 μm ka mānoanoa a mānoanoa paha) hana nui ma ke ʻano he mau papa pale, akā hoʻomaikaʻi pū i ka hoʻopili ʻana a me ka paʻa no nā uhi papa lahilahi ma hope. ʻO nā uhi papa lahilahi e komo pū me ka silicon dioxide (SiO2), tantalum oxide, titanium oxide, aluminum oxide, niobium oxide, a me nā hafnium oxides (SiO2, Ta2O5, TiO2, Al2O3, Nb3O5, a me HfO2); ʻo nā uhi aniani metala maʻamau he alumini (Al), kālā (Ag), a me ke gula (Au). ʻAʻole hoʻohana pinepine ʻia ka Fluoride a i ʻole nitride no ka uhi ʻana, no ka mea, no ka loaʻa ʻana o ka maikaʻi o ka uhi ʻana, pono ka wela kiʻekiʻe, kahi mea i kūpono ʻole me nā kūlana waiho wela haʻahaʻa e pono ai no ka uhi ʻana i nā ʻāpana plastik.

I ka wā e noʻonoʻo ai ke kaumaha, ke kumukūʻai a me ka maʻalahi o ka ʻākoakoa ʻana no ka hoʻohana ʻana i nā ʻāpana optical, ʻo nā ʻāpana optical plastik ke koho maikaʻi loa.

Nā optics noʻonoʻo i hoʻopilikino ʻia no kahi scanner kūikawā, nona kahi ʻano o nā ʻāpana poepoe a me nā ʻāpana poepoe ʻole (Alumini i uhi ʻia a me ka uncoated).

ʻO kekahi wahi hoʻohana maʻamau no nā ʻāpana optical plastik i uhi ʻia ʻo ia ka maka aniani. I kēia manawa, he mea maʻamau loa nā uhi anti-reflective (AR) ma nā aniani maka, me ka ʻoi aku ma mua o 95% o nā aniani maka āpau e hoʻohana ana i nā aniani plastik.

ʻO kekahi kahua noi no nā ʻāpana optical plastik ʻo ia ka lako lele. No ka laʻana, i loko o kahi noi hōʻike poʻo-i luna (HUD), he mea nui ka noʻonoʻo ʻana i ke kaumaha o ka ʻāpana. He kūpono nā ʻāpana optical plastik no nā noi HUD. E like me nā ʻōnaehana optical paʻakikī ʻē aʻe, pono nā uhi antireflective i nā HUD e pale aku i ka mālamalama i hoʻopuehu ʻia e nā hoʻokuʻu hewa. ʻOiai hiki ke uhi ʻia nā kiʻiʻoniʻoni hoʻonui oxide metala a me nā papa he nui, pono ka ʻoihana e hoʻomohala mau i nā ʻenehana hou e kākoʻo i nā ʻāpana optical plastik i nā noi hou aʻe.
