He rerekē ngā hoahoa o ngā karāhe whatu, ko te nuinga he porowhita, he āporo, he āporo takirua. He rerekē ngā āhuatanga whatu, ngā matotoru, me ngā āhuatanga mahi tirohanga o ia momo. Mā te mārama ki ēnei rerekētanga ka āwhina i te whiriwhiri i ngā karāhe e tika ana i runga i te kaha o te karāhe, te whakamarie, me ngā manakohanga ataahua.
1. Ngā Arotahi Porowhita
He rite te piko o ngā karāhe porowhita puta noa i te mata katoa, he rite ki tētahi wāhanga o te porowhita. He māmā noa te hanga i tēnei hoahoa tuku iho, ā, e whakamahia whānuitia ana.
Ngā Painga:
• He iti te utu, he mea tino pai mō ngā kaihoko e whai whakaaro ana ki te tahua.
• He pai mō ngā rongoā iti ki te taurite, me te iti o te hē.
Ngā ngoikoretanga:
• He matotoru ake ngā tapa, inā koa mō ngā rongoā teitei ake, ka hua ake he taumaha ake, he matotoru ake hoki ngā mōhiti.
• Te pikinga ake o te hē o te taha (te hē o te tirohanga porowhita), ka pōuri, ka hē rānei te tirohanga ki ngā taha.
• Kāore i te tino ātaahua te titiro nā te piko o te mata, ka āhua whakanuia, ka whakaititia rānei ngā kanohi.
2. Ngā Arotahi Āporo
He papatahi haere te piko o ngā karāhe aspheric ki ngā taha, ka whakaiti i te matotoru me ngā hē o te tirohanga ki te whakaritea ki ngā karāhe porowhita.
Ngā Painga:
• He angiangi ake, he māmā ake, e whakarei ake ana i te whakamarie, inā koa mō ngā rongoā kaha ake.
• Ka whakaitihia te hē o te tirohanga taha, ka pai ake, ka tūturu ake hoki te tirohanga.
• He ātaahua ake te āhua, nā te mea ka whakaitihia te pānga "pupuhi" e te āhua papatahi.
Ngā ngoikoretanga:
• He nui ake te utu i ngā karaihe porowhita nā te uaua o te hanga.
• Tērā pea ka hiahiatia he wā poto mō ētahi kaimau ki te urutau nā te rerekētanga o te āhua o te karu arotahi.
3. Ngā Arotahi Āporo Takirua
Ka whakatairangahia e ngā karāhe āporo rua te arotautanga mā te whakauru i ngā kōpiko āporo ki ngā mata o mua me muri. Ka whakanuia e tēnei hoahoa matatau te mahi whatu me te whakaiti i te matotoru.
Ngā Painga:
• Tino angiangi, tino māmā hoki, ahakoa mō ngā whakahaunga nui.
• He māramatanga whatu tino pai puta noa i te arotahi katoa, me te iti o ngā hapa.
• Ko te āhua papatahi, ā, he āhua tūturu, he mea tino pai mō te hunga e mau ana i te āhua huatau.
Ngā ngoikoretanga:
• Ko te utu nui rawa atu i roto i ngā mea e toru nā te hangarau tika.
• Me ine tika, me taunga hoki kia tino pai ai te mahi.
Te Kōwhiri i te Arotahi Tika
• Ko ngā karaihe porowhita te mea pai mō te hunga he iti noa ngā rongoā me ngā herenga pūtea.
• He pai te taurite o te utu, te whakamarie, me te kounga tirohanga mā ngā karu arotahi Aspheric mō ngā rongoā reo-waenga ki te reo-tiketike.
• Ko ngā karāhe arotahi takirua he mea whiriwhiri pai mō te hunga whai tohu pai, e aro nui ana ki te ataahua me te tika o te tirohanga.
I te whanaketanga o te hangarau arotahi, kei te piki haere te rongonui o ngā hoahoa aspheric. Mā te kōrero ki tētahi tohunga tiaki kanohi ka taea te āwhina i te whakatau i te kōwhiringa pai rawa atu i runga i ngā hiahia me te momo noho o te tangata takitahi.
Kua whakapau kaha tonu a Universe Optical ki te auahatanga hangarau i roto i ngā hua arotahi, e whakarato ana i ngā kōwhiringa kanorau ki ngā kiritaki hei whakatutuki i ngā hiahia e whanake haere ana.
