Ko te tino ataahua o te mōrahi karāhe-rua-kanohi kei roto i tōna kaha whakaputa hiko hou. Kāore i rite ki ngā mōrahi taha-kotahi tuku iho, ka taea e tōna tuara te hopu i te mārama whakaata o te whenua (pēnei i te onepu, te hukarere, ngā tuanui tae mārama, ngā papa sima rānei), ka nui ake te whakaputa hiko. E mōhiotia ana tēnei i roto i te umanga ko te "whakanui taha-rua". I tēnei wā, ko te ōwehenga mata-rua (te ōwehenga o te whai huatanga whakaputa hiko i te tuara ki te taha o mua) o ngā hua matua ka eke ki te 85% ki te 90%. Hei tauira, i roto i ngā taiao whakaata-nui pērā i te koraha, ka taea e te whakanui taha-muri o ngā wāhanga te whakapiki i te whakaputa hiko whānui mā te 10%-30%. I taua wā, ka pai ake te mahi a tēnei momo wāhanga i raro i ngā āhuatanga iti o te hihi (pēnei i ngā rā ua, i te ata pō me te ahiahi pō rānei), me te whakanui hiko neke atu i te 2%.
Ko te auahatanga o ngā rauemi me ngā hanganga te mea nui hei tautoko i te whakaputa hiko whai hua. Ko ngā hangarau pākahiko matatau (pēnei i te TOPCon momo-N) kei te akiaki i te kaha o ngā wāhanga kia piki tonu, ā, kua uru ngā hua matua ki te awhe 670-720W. Hei whakaiti i te ngaronga o te atarangi o mua me te whakarei ake i te pai o te kohikohinga o te au, kua whakauruhia e te umanga ngā hoahoa kore-kiko matua (pēnei i te hanganga 20BB) me ngā hangarau tā kua whakapaitia (pēnei i te tā mata maitai). I te taumata takai, ko te hanganga karāhe-rua (me te karāhe i mua me muri) e tuku ana i te tiakitanga tino pai, e pupuri ana i te whakaiti i te tau tuatahi o te wāhanga i roto i te 1% me te reiti whakaiti ā-tau toharite i raro i te 0.4%, he mea pai ake i ngā wāhanga karāhe-kotahi tuku iho. Hei whakatika i te wero o te taumaha nui o ngā kōwae karāhe-rua (ina koa ko ngā mea nui), i puta mai he otinga pepa muri mārama māmā, e taea ai te whakaiti i te taumaha o ngā kōwae 210-rahi ki raro iho i te 25 kirokaramu, e whakaiti ana i ngā uauatanga tāutanga.
Ko te āheinga ki te urutau ki te taiao tētahi atu painga nui o te waeine karāhe-rua-taha. Nā tōna hanganga karāhe-rua pakari ka tino ātete ki te huarere, ka ātete pai ki te whakaiti i te kaha hiko (PID), ki ngā hihi ultraviolet kaha, ki te pānga o te whatu, ki te haumākū teitei, ki te waikura rehu tote, me ngā rerekētanga pāmahana nui. Mā te whakatū i ngā teihana hiko whakaaturanga i roto i ngā rohe āhuarangi rerekē huri noa i te ao (pēnei i te makariri nui, te hau kaha, te pāmahana teitei me te haumākū teitei), kei te manatoko tonu ngā kaihanga wāhanga i ō rātou kaha mahi pumau mō te wā roa i roto i ngā taiao tino kino.
