ʻOiai ke ʻano o kahi kahua granite e like me kahi papa pōhaku maʻalahi, loli nui nā pae koho i ka neʻe ʻana mai nā noi ʻoihana maʻamau i ka nānā ʻana o ka optical kiʻekiʻe a me ka metrology. No ZHHIMG®, ʻo ka hoʻolako ʻana i nā ʻāpana kikoʻī i nā alakaʻi honua i ka semiconductor a me ka ʻenehana laser ʻo ia hoʻi ka ʻike ʻana ʻaʻole kahi kahua no ke ana ʻana o ka optical he kumu wale nō—he ʻāpana koʻikoʻi ia, ʻaʻole hiki ke kūkākūkā ʻia o ka ʻōnaehana optical ponoʻī.
ʻO nā koi no ka nānā ʻana i ka ʻike maka—ʻo ia hoʻi ke kiʻi hoʻonui kiʻekiʻe, ka nānā ʻana i ka laser, a me ka interferometry—ua wehewehe ʻia e ka pono e hoʻopau i nā kumu āpau o ka walaʻau ana. Ke alakaʻi nei kēia i ka nānā ʻana i ʻekolu mau waiwai kūikawā e hoʻokaʻawale i kahi kahua ʻike maka maoli mai kahi kahua ʻoihana maʻamau.
1. ʻOi aku ka nui o ka Density no ka Damping Haʻalulu Kūlike ʻole
No nā kumu CNC ʻoihana maʻamau, hiki i ka hao i hoʻolei ʻia a i ʻole ka granite maʻamau ke hāʻawi i ka paʻakikī kūpono. Eia nō naʻe, ʻike nui ʻia nā hoʻonohonoho optical i nā neʻe minuke i hoʻokumu ʻia e nā haʻalulu o waho mai nā lako hana hale hana, nā ʻōnaehana lawelawe ea, a i ʻole ke kaʻa mamao.
ʻO kēia kahi e lilo ai ka ʻepekema mea i mea nui loa. Pono kahi kahua optical i ka granite me ka damping mea kūlohelohe kūikawā. Hoʻohana ʻo ZHHIMG® i kāna ZHHIMG® Black Granite ponoʻī (≈ 3100 kg/m³). ʻO kēia mea ultra-high-density, ʻaʻole e like me ka granite haʻahaʻa a i ʻole nā mea pani marble, loaʻa iā ia kahi ʻano crystalline i kūpono loa i ka hoʻokuʻu ʻana i ka ikehu mechanical. ʻAʻole wale ka pahuhopu e hōʻemi i ka haʻalulu, akā e hōʻoia i ka noho ʻana o ke kumu i kahi papahele mechanical mālie loa, e hoʻemi ana i ka neʻe pili ma waena o ka lens objective a me ka laʻana i nānā ʻia ma ka pae sub-micron.
2. Ke kūpaʻa wela loa e hakakā ai i ka Drift
Hoʻomanawanui nā kahua ʻoihana maʻamau i nā loli liʻiliʻi o ka nui; ʻaʻole paha he mea nui ka hapaʻumi o ke kekelē Celsius no ka ʻeli ʻana. Akā i loko o nā ʻōnaehana optical e hana ana i nā ana pololei ma luna o nā wā lōʻihi, ʻo kēlā me kēia drift thermal i ke geometry o ke kumu e hoʻolauna i ka hewa ʻōnaehana.
No ka nānā ʻana i ka ʻike maka, pono kahi kahua e hana ma ke ʻano he poho wela me kahi coefficient haʻahaʻa loa o ka hoʻonui ʻana i ka wela (CTE). ʻO ka nuipaʻa kiʻekiʻe a me ka nui o ZHHIMG® Black Granite e hāʻawi i ka inertia wela e pono ai e pale aku i nā hoʻonui minuke a me nā ʻūlū e hiki ke hana i loko o kahi lumi i kāohi ʻia e ke aniau. Hōʻoia kēia kūpaʻa e paʻa mau ka mamao o ka nānā ʻana i hoʻoponopono ʻia a me ka hoʻonohonoho planar o nā ʻāpana optical, e hōʻoiaʻiʻo ana i ka pono o nā ana e pili ana i nā hola—he mea hiki ʻole ke kūkākūkā ʻia no ka nānā ʻana i ka wafer hoʻonā kiʻekiʻe a i ʻole ka metrology hōʻike pālahalaha.
3. Ke hoʻokō nei i ka Nano-Level Flatness a me ka Geometric Precision
ʻO ka ʻokoʻa i ʻike nui ʻia ʻo ia ke koi no ka pālahalaha. ʻOiai hiki i kahi kahua ʻoihana maʻamau ke hoʻokō i ka pālahalaha Papa 1 a i ʻole Papa 0 (i ana ʻia i loko o kekahi mau microns), koi nā ʻōnaehana optical i ka pololei ma ka pae nanometer. Pono kēia pae o ka hemolele geometric e hāʻawi i kahi mokulele kuhikuhi hilinaʻi no nā pae linear a me nā ʻōnaehana autofocus e hana ana ma nā kumumanaʻo o ka hoʻopilikia ʻana o ka mālamalama.
ʻO ka hoʻokō ʻana a me ka hōʻoia ʻana i ka palahalaha o ka pae nanometer e pono ai kahi ʻano hana ʻokoʻa loa. Pili ia i nā ʻenehana kūikawā loa e hoʻohana ana i nā mīkini holomua e like me nā wili Taiwan Nanter a ua hōʻoia ʻia e nā lako metrology akamai e like me Renishaw Laser Interferometers. Pono e hana ʻia kēia kaʻina hana ma kahi ʻano paʻa loa, e like me nā hale hana i hoʻomalu ʻia e ka haʻalulu a ZHHIMG®, kahi e hoʻemi ʻia ai nā neʻe liʻiliʻi o ka lewa.
ʻO ke kumu, ʻo ke koho ʻana i kahi kahua granite precision no ka nānā ʻana i ka optical he hoʻoholo ia e hoʻokomo i kahi ʻāpana e hōʻoiaʻiʻo ana i ka pololei o ke ana optical ponoʻī. Pono ia e hui pū me kahi mea hana e nānā ana i ka palapala hōʻoia ISO 9001 a me ka hiki ke hoʻopili ʻia ka dimensional ʻaʻole ma ke ʻano he mau hiʻohiʻona koho, akā ma ke ʻano he mau koi kumu no ke komo ʻana i ke ao o nā optics ultra-precision.
