1. Muka maha-aratau
Ina nui ake te rahi āhuahanga o te muka (te whānui matua d1) i te roanga ngaru o te mārama (tata ki te 1 µm), ka maha, ka rau rānei ngā momo horapa i roto i te muka. He rerekē te tere me te āhua o ngā momo horapa, ā, ka hua ake he whakaroa wā me te whakanui i ngā pāoro whatu i muri i te tuku tawhiti. Ka kiia tēnei āhuatanga ko te mararatanga aratau (e mōhiotia ana ko te mararatanga intermodal). muka whatu.
Ka whakawhāitihia te whānui o te muka aratau maha e te mararatanga aratau, ā, ka whakaitihia tōna kaha tuku, nō reira he pai anake te muka aratau maha mō ngā whakawhitiwhitinga muka whatu iti te kaha.
Ko te tohatoha o te taupū whakaata o te muka maha-aratau he parabolic te nuinga, arā, he taupū whakaata kua whakarōpūtia. Ko te whānui o tōna matua he tata ki te 50 µm.
2. Muka aratau-kotahi
Ina tata te rahi āhuahanga o te muka (te whānui o te matua) ki te roanga ngaru o te mārama, hei tauira, kei roto i te awhe 5-10 µm te whānui o te matua d1, kotahi noa te aratau (aratau taketake HE11) ka taea e te muka te horapa i roto, ā, ka tapahia ngā aratau teitei ake; ka kiia aua muka he muka aratau kotahi.
Nā te mea kotahi anake te aratau horapa, ā, ka karohia te raruraru o te marara aratau, he whānui rawa te whānui o te muka aratau-kotahi, ā, he tino pai mō ngā whakawhitiwhitinga muka whatu kaha-teitei. Nō reira, kia tutuki ai te tuku aratau-kotahi, me tutuki i ngā tawhā muka ētahi tikanga. Ka tatauhia mā te whakamahi i te tātai, arā, mō te muka me te NA=0.12, kia tutuki ai te tuku aratau-kotahi i runga ake i te λ=1.3 µm, me ≤4.2 µm te radius o te matua muka, arā, ko te diameter o tōna matua d1≤8.4 µm.
Nā te iti rawa o te diameter matua o te muka whatu aratau-kotahi, ka whakatakotoria he whakaritenga pakari ake mō tōna tukanga hanga.
