I hangaia tuatahitia te hangarau whakakore waikura i te tekau tau atu i 1950. I roto i te tukanga whakawhanaketanga o ngā mīhini whakakore waikura, e toru ngā wā nui kua pahure. Whāia tēnei tuhinga kia mārama ai koe.
(1) Mīhini whakakore kiri tuatahi
Ka whakamahia te pūwero tio hei ipu mahi mō ngā tapa tio, ā, ka whiriwhiria tuatahitia te huka maroke hei whakamatao. Ka utaina ngā wāhanga hei whakatika ki roto i te pūwero, me te tāpiri pea i ētahi rauemi mahi taupatupatu. Ka whakahaeretia te pāmahana i roto i te pūwero kia tae ki te āhua pakarukaru o ngā taha, engari kāore te hua e pāngia. Hei whakatutuki i tēnei whāinga, me ≤0.15mm te matotoru o ngā taha. Ko te pūwero te wāhanga matua o te taputapu, ā, he āhua waru-kōtaha. Ko te mea nui ko te whakahaere i te pūwāhi pānga o te rauemi i panaia, kia taea ai te huri haere tonu.
Ka huri te pahu i te taha maui ki te karaka kia takahuri, ā, i muri i tētahi wā, ka pakarukaru ngā taha kanapa, ā, ka oti te mahi tapa. Ko te hapa o te tapa tio o te whakatupuranga tuatahi ko te tapa kāore i oti, inā koa ko ngā taha kanapa toenga i ngā pito o te rārangi wehewehe. Nā te hoahoa pokepokea koretake, te matotoru rawa rānei o te paparanga rapa i te rārangi wehewehe (neke atu i te 0.2mm) tēnei.
（2）Te mīhini whakaweto kiri tuarua
E toru ngā whakapainga kua mahia e te mīhini whakamātao cryogenic tuarua i runga i te whakatupuranga tuatahi. Tuatahi, ka hurihia te hauota wai hei hauota wai. Kāore te huka maroke, me te ira whakangawari o te -78.5°C, e pai mō ētahi rapa pakarukaru pāmahana iti, pērā i te rapa silicone. Ko te hauota wai, me te ira kohua o te -195.8°C, e pai ana mō ngā momo rapa katoa. Tuarua, kua whakapaingia te ipu e pupuri ana i ngā wāhanga hei kuti. Ka hurihia mai i te pahu hurihuri ki te whitiki kawe āhua-awa hei kawe. Mā tēnei ka taea e ngā wāhanga te takahuri i roto i te awaawa, ka whakaitihia te putanga mai o ngā ira mate. Ehara i te mea ka whakapai ake i te pai o te mahi engari ka whakarei ake hoki i te tika o te taha. Tuatoru, hei utu mō te whakawhirinaki anake ki te tukinga i waenga i ngā wāhanga hei tango i ngā taha kanapa, ka whakauruhia he rauemi pupuhi pai. Ka pupuhihia ngā pire whakarewa, kirihou mārō rānei me te rahi matūriki o te 0.5~2mm ki te mata o ngā wāhanga i te tere raina o te 2555m/s, ka hanga he kaha pānga nui. Mā tēnei whakapainga ka tino whakapoto i te wā huringa.
（3）Te mīhini whakakore kiripaka tuatoru
Ko te tuatoru o ngā mīhini whakakore i ngā mea e whakamahia ana hei whakapai ake i runga i te whakatupuranga tuarua. Ka hurihia te ipu mō ngā wāhanga hei kuti ki tētahi kete wāhanga me ngā pakitara poka. Ka kapi ēnei kōhao i ngā pakitara o te kete me te diameter o te 5mm (nui ake i te diameter o ngā pere) kia taea ai e ngā pere te haere marie i roto i ngā kōhao, ka taka ki runga o te taputapu hei whakamahi anō. Ehara i te mea ka whakawhānui noa i te kaha whai hua o te ipu, engari ka whakaitihia hoki te rahinga rokiroki o ngā pāpāho pānga (ngā pere). Kāore te kete wāhanga i te tū poutū i roto i te mīhini kuti, engari he piko (40°~60°). Mā tēnei koki piko ka huri kaha te kete i te wā o te tukanga taha nā te whakakotahitanga o ngā kaha e rua: ko tētahi ko te kaha hurihuri e whakaratohia ana e te kete tonu e takahuri ana, ko tētahi ko te kaha porotītaha i hangaia e te pānga pere. Ina whakakotahihia ēnei kaha e rua, ka puta he nekehanga 360° omnidirectional, ka taea ai e ngā wāhanga te tango i ngā taha mura kia ōrite, kia tino tangohia i ngā taha katoa.
