No ke aha e koho ai i ka granite ma kahi o ka metala e hana i nā ʻāpana mechanical nānā optical aunoa.

I ka wā e pili ana i ka hana ʻana i nā ʻāpana mīkini nānā optical aunoa, kahi nīnau maʻamau e kū mai ana inā e hoʻohana i ka granite a i ʻole ka metala no ka hana ʻana. ʻOiai ʻo nā metala a me ka granite ko lākou mau pono a me nā hemahema, aia kekahi mau pono o ka hoʻohana ʻana i ka granite no nā ʻāpana mīkini nānā optical aunoa.

ʻO ka mea mua, he pōhaku kūlohelohe ka granite i ʻike ʻia no kona ikaika, kūpaʻa, a me ke kūpaʻa. ʻO ia ka lua o ka pōhaku kūlohelohe paʻakikī ma hope o ke daimana a he kūpaʻa kiʻekiʻe i ka ʻaʻahu a me ka abrasion. ʻO kēia ka mea maikaʻi loa no ka hana ʻana i nā ʻāpana e pono ai ka pololei a me ka pololei, e like me nā mīkini nānā optical.

ʻO ka lua, he kūpaʻa maikaʻi loa ka granite i ka dimensional, ʻo ia hoʻi ke kūpaʻa mau nei ʻoiai ke hōʻike ʻia i nā mahana like ʻole a me nā pae haʻahaʻa. He mea koʻikoʻi kēia no ka mea hiki i nā ʻāpana mīkini i hana ʻia me ka metala ke hoʻonui a ʻuʻuku paha i ka wā e kau ʻia ai nā loli o ka mahana, hiki ke hana i nā hewa nui i nā ana. Ma ka ʻaoʻao ʻē aʻe, mālama ka granite i kona ʻano a me ka nui, e hōʻoiaʻiʻo ana e pololei a maikaʻi ka mīkini nānā optical aunoa.

ʻO ke kolu, he mau waiwai damping maikaʻi ko ka granite, kahi e hiki ai iā ia ke omo i nā haʻalulu a hōʻemi i ka resonance. He mea nui kēia i loko o kahi mea ana kiʻekiʻe kahi e hiki ai i ka haʻalulu liʻiliʻi a i ʻole ka haʻalulu ke hoʻopilikia i ka pololei o ke ana. ʻO ka hoʻohana ʻana i ka granite i ka hoʻolālā ʻana i nā ʻāpana mechanical o nā mīkini nānā optical aunoa e hōʻoiaʻiʻo ana hiki iā lākou ke kū i nā pae kiʻekiʻe o ka haʻalulu a mālama i ko lākou pololei.

Eia kekahi, he kūpaʻa maikaʻi loa ka granite i ka pala, e kūpono ai no ka hoʻohana ʻana i nā wahi ʻino a i ʻole nā ​​​​​​wahi ʻoihana e pono ai nā mea paʻa a kūpaʻa. He maʻalahi hoʻi e hoʻomaʻemaʻe a mālama, kahi e kōkua ai i ka hoʻonui ʻana i ke ola o ka mīkini.

I ka hopena, ʻoiai he mea kūpono hoʻi ka metala no ka hana ʻana i nā ʻāpana mīkini, ʻo ka granite ka mea makemake ʻia no ka hana ʻana i nā ʻāpana mīkini nānā optical aunoa. ʻO nā waiwai kūlohelohe o ka granite, e like me kona kūpaʻa, ke kūpaʻa dimensional, nā waiwai damping, a me ke kūpaʻa ʻana i ka corrosion, e lilo ia i mea kūpono no ka ʻenekinia pololei a me ka hana ʻana. Eia kekahi, ʻo ka hoʻohana ʻana i ka granite e hāʻawi i kahi kiʻekiʻe o ka pololei a me ka hilinaʻi i nā ana, he mea nui ia i nā mīkini nānā optical aunoa. No laila, ʻo nā ʻoihana e koi ana i nā mīkini nānā optical aunoa kiʻekiʻe e noʻonoʻo i ka granite ma ke ʻano he koho kūpono no ka hana ʻana i kā lākou mau mīkini.
