He wāhanga whatu mārama ngā karāhe whatu, he mata piko, ka taea te huripoki me te arotahi i te mārama. He whānuitia te whakamahinga i roto i ngā pūnaha whatu hei whakahaere i ngā hihi mārama, hei whakatika i te tirohanga, hei whakanui i ngā mea, hei hanga whakaahua. He wāhanga nui ngā karāhe whatu i roto i ngā kāmera, i ngā karu tiro, i ngā karu iti, i ngā mōhiti tirohanga, i ngā pūwhakaata, me te maha atu o ngā taputapu whatu.

E rua ngā momo matua o ngā karaihe arotahi:

Ngā karaihe kōpiko (kātahi rānei)He matotoru ake ēnei karāhe arotahi i waenganui i ngā taha, ā, ka huihuia ngā hihi mārama whakarara e tika ana mā roto i a rātou ki tētahi pūwāhi arotahi i te taha ke o te karāhe arotahi. He mea noa te whakamahi i ngā karāhe arotahi kōpikopiko i roto i ngā karāhe whakanui, ngā kāmera, me ngā mōhiti tirohanga hei whakatika i te tirohanga tawhiti.

Ngā karaihe kōpiko (ngā karaihe wehewehe rānei)He angiangi ake te pokapū o ēnei karāhe i ngā taha, ā, ka meinga e rātou ngā hihi mārama whakarara e tika ana kia wehea, me te mea nei kei te ahu mai i tētahi pūwāhi arotahi mariko i te taha kotahi o te karāhe. He maha ngā wā ka whakamahia ngā karāhe kōpiko hei whakatika i te tirohanga tata.

Ka hangaia ngā karu arotahi i runga i te roa o te arotahi, arā, te tawhiti mai i te karu arotahi ki te pūwāhi arotahi. Ko te roa arotahi te mea e whakatau ana i te nui o te piko o te mārama me te hanganga o te ahua ka puta.

Ko ētahi o ngā kupu matua e pā ana ki ngā karāhe whatu ko:

Pūwāhi arotahiKo te pūwāhi e tūtaki ai ngā hihi mārama, e āhua wehe kē ana rānei i muri i te whiti i roto i te karu arotahi. Mō te karu arotahi pūkohu, koinei te pūwāhi e tūtaki ai ngā hihi whakarara. Mō te karu arotahi kōpiko, koinei te pūwāhi e āhua puta mai ai ngā hihi wehewehe.

Roanga arotahiKo te tawhiti i waenganui i te arotahi me te pūwāhi arotahi. He tawhā nui tēnei e tautuhi ana i te kaha o te arotahi me te rahi o te ahua i hangaia.

PūahaKo te whānui o te karu arotahi e taea ai te whiti te mārama. Mā te whakatuwheratanga nui ake ka nui ake te mārama e whiti, ka mārama ake te ahua.

Tuaka whatuKo te rārangi pokapū e tika ana mā waenganui o te arotahi poutū ki ōna mata.

Mana arotahiKi te inehia ki ngā diopters (D), ko te kaha o te arotahi e tohu ana i te kaha whakaata o te arotahi. He kaha pai ngā arotahi pūkohu, he kaha kino ia ngā arotahi kōpiko.

Kua hurihia e ngā karāhe whatu ngā momo mara, mai i te whetū arorangi ki ngā pūtaiao hauora, mā te āhei i a tātou ki te tirotiro i ngā mea tawhiti, ki te whakatika i ngā raruraru tirohanga, me te mahi whakaahua me ngā ine tika. He mea nui tonu tā rātou mahi ki te whakatairanga i te hangarau me te tūhuratanga pūtaiao.
