He kaha te kiri noa ki te mimiti i te mārama hei tiaki i ngā okana me ngā kiko o te tinana mai i te kino o te mārama. Ko te kaha o te mārama ki te tomo ki te kiko tangata he hononga tata ki tōna roangaru me te hanganga o te kiko kiri. I te nuinga o te wā, ko te poto o te roangaru, ko te papaku o te urunga ki roto i te kiri. Ka mimiti te kiko kiri i te mārama me te whiriwhiri mārama. Hei tauira, ka taea e ngā keratinocytes i roto i te stratum corneum te mimiti i te nui o ngā hihi ultraviolet poto-ngaru (ko te roangaru he 180~280nm), ā, ko ngā pūtau spinous i roto i te papa spinous me ngā melanocytes i roto i te papa turanga ka mimiti i ngā hihi ultraviolet roa-ngaru (ko te roangaru he 320 nm~400nm). He rerekē te mimiti o te kiko kiri i ngā roangaru rerekē o te mārama, ā, ko te nuinga o ngā hihi ultraviolet ka mimitihia e te kiriuhi kiri. I te pikinga o te roangaru, ka rerekē anō hoki te nui o te urunga o te mārama. Ka uru ngā hihi infrared e tata ana ki te mīhini rama whero ki roto i ngā papa hohonu o te kiri, engari ka mimitihia e te kiri. Ko te infrared roa-ngaru (ko te roangaru he 15~400μm) ka tino ngoikore te urunga, ā, ko te nuinga ka mimitihia e te kiriuhi kiri.
Ko te kaupapa matua o runga ake nei ko tetātari kirika taea te whakamahi hei kite i ngā raruraru kiri hōhonu. Ko tetātari kiriKa whakamahia ngā momo irahiko rerekē (RGB, te mārama whakawhiti-polarized, te mārama whakarara-polarized, te mārama UV me te mārama Wood) hei hanga i ngā roangaru rerekē hei kimi i ngā raruraru kiri mai i te mata ki te paparanga hohonu ake, kia taea ai e te tātari kiri te kite i ngā kita, ngā uaua pungawerewere, ngā pūwero nui, ngā ira mata, ngā ira hohonu, te tae kiri, te tae kiri, te mumura, ngā porphyrin me ētahi atu raruraru kiri.
