Hoʻohana i nā ʻāpana granite pololei i ka ʻoihana optical.

 

Ua lōʻihi ka ʻoihana optical ma mua o ka holomua ʻenehana, e koi ana i nā mea e hiki ke hoʻokō i nā koi koʻikoʻi no ka pololei a me ka paʻa. ʻO kekahi mea i kaulana nui ʻia ʻo ka granite precision. ʻIke ʻia no kona ʻano paʻakikī, hoʻonui haʻahaʻa wela, a me ke kūpaʻa maoli, ua lilo ka granite i mea koho maikaʻi loa no nā noi like ʻole i loko o ka ʻāpana optical.

Hoʻohana ʻia nā ʻāpana granite pololei i ka hana ʻana i nā mea hana optical, e like me nā telescopes, microscopes, a me nā ʻōnaehana laser. ʻO nā waiwai kūʻokoʻa o ka granite e ʻae i ka hana ʻana i nā kumu paʻa a me nā mauna e hiki ke kū i ka fluctuations kaiapuni me ka ʻole e hoʻololi i ka pololei o nā alignments optical. He mea koʻikoʻi kēia kūpaʻa, no ka mea, hiki i ka haʻalele iki ke alakaʻi i nā hewa nui i nā ana a me nā kiʻi.

Eia kekahi, ʻo ke ʻano porous ʻole o ka granite a me ke kūpaʻa ʻana i ka ʻaʻahu e lilo ia i mea kūpono no nā papaʻaina a me nā paepae. Hāʻawi kēia mau ʻili i kahi hopena vibration-dampening, he mea nui ia no nā hoʻokolohua optical kiʻekiʻe. Ma ka ho'ēmiʻana i nā pilikia o waho, hiki i nā mea noiʻi ke hoʻokō i nā hopena hilinaʻi, e hoʻonui i ka maikaʻi o nā huahana optical.

Ma waho aʻe o kāna mau waiwai mechanical, hiki ke hana ʻia ka granite precision e hoʻokō i nā tolerances paʻa loa. He mea nui kēia mana no ka hana ʻana i nā ʻāpana optical e koi ana i nā ana kikoʻī no ka hana maikaʻi loa. ʻO ka hiki ke hana i nā ʻano like ʻole a me nā nui e hoʻonui hou i ka noi ʻana o ka granite i ka ʻoihana optical, e ʻae ana i nā hoʻolālā hou e kūpono i nā koi o ka papahana.

Ke hoʻomau nei ka noi no nā ʻōnaehana optical kiʻekiʻe, e hoʻonui paha ka noi o nā ʻāpana granite precision. Me ka holomua o ka ʻenehana mīkini a me ka ʻepekema waiwai, e noho mau ka granite i pōhaku kihi i ka hoʻomohala ʻana i nā mea hana optical ʻokiʻoki, e hōʻoia ana e hiki i ka ʻoihana ke hoʻokō i nā pilikia o ka wā e hiki mai ana me ka pololei a me ka hilinaʻi.
