Ine tautoko:honoa ki te pūmanawa ine hei whakatutuki i te inenga āhuahanga tika.

E ai ki ngā whakaritenga tono rerekē, ka taea te wehewehe i ngā karu karu ā-ahumahi ki ngā kāwai e whai ake nei:

(1) Te whakarōpūtanga mā te whakanui

Arotahi iti-manaKo te whakanui i te nuinga o te wā kei waenga i te 1x-10x, he mea pai mō te mātakitaki i ngā mea nunui ake, i ngā hanganga whānui rānei.

Arotahi mana-waengaKei waenga i te 10x ki te 50x te whakanui, he pai mō te mātakitaki i ngā taipitopito rahi-waenga.

Arotahi kaha-teiteiKei waenga i te 50x ki te 1000x, neke atu rānei te whakanui, he pai mō te mātakitaki i ngā taipitopito ririki, i ngā hanganga moroiti rānei.

(2)Te whakarōpūtanga mā te hoahoa whatu

Karāhe ā-taeKua whakatikatikahia te he o te tae, he pai mō te tirotiro whānui.

(3) Te whakarōpūtanga mā te tawhiti mahi

Arotahi tawhiti mahi roaHe tawhiti mahi roa, he pai mō te tirotiro i ngā wāhi teitei, mō te whakamahi rānei.

Arotahi tawhiti mahi potohe poto te tawhiti mahi, ā, he pai mō te mātakitaki i te whakanui teitei.

(4) Te whakarōpūtanga mā te mahi motuhake

Karāhe whakapolarisasi: e whakamahia ana hei tirotiro i ngā rauemi he āhuatanga birefringence, pērā i ngā tioata, ngā muka, me ētahi atu.
