Indlela yokubuka insimu ekhanyayo kanye nendlela yokubuka insimu emnyama izindlela ezimbili ezivamile ze-microscopy, ezinezinhlelo zokusebenza ezihlukene kanye nezinzuzo ezinhlotsheni ezahlukene zokubhekwa kwesampula. Okulandelayo incazelo eningiliziwe yezindlela ezimbili zokubuka.
Indlela Yokubheka Inkambu Ekhanyayo:
Indlela yokubuka inkundla ekhanyayo ingenye yezindlela eziyisisekelo futhi ezisetshenziswa kakhulu zama-microscopy. Ekubukeni kwensimu ekhanyayo, isampula sikhanyiswa ngokukhanya okudlulisiwe, futhi isithombe sakhiwe ngokusekelwe kubukhulu bokukhanya okudlulisiwe. Le ndlela ifanele izibonelo eziningi zebhayoloji ezivamile, njengezingcezu zethishu enamabala noma amaseli.
Izinzuzo:
Kulula ukusebenza futhi kusebenza kunhlobonhlobo yamasampula ebhayoloji ne-inorganic.
Inikeza umbono ocacile wesakhiwo sonke sezibonelo zezinto eziphilayo.
Ububi:
Ayiwafanele amasampuli abonisa ngale nangenambala, njengoba evame ukuntula umehluko, okwenza kube inselele ukuthola izithombe ezicacile.
Ayikwazi ukuveza izakhiwo zangaphakathi ezinhle ngaphakathi kwamaseli.
Indlela Yokubheka Indawo Emnyama:
Ukubuka kwenkambu emnyama kusebenzisa ilungiselelo lokukhanyisa elikhethekile ukuze kwakhe ingemuva elimnyama elizungeze isampula. Lokhu kubangela isampula ukuthi ihlakazeke noma ibonise ukukhanya, okuholela esithombeni esikhanyayo ngokumelene nengemuva elimnyama. Le ndlela ifaneleka ngokukhethekile kumasampuli abonisa ngale nangenambala, njengoba ithuthukisa imiphetho namakhonsa wesampula, ngaleyo ndlela ikhulise ukugqama.
Isisetshenziswa esikhethekile esidingekayo ukuze kubonwe insimu emnyama i-condenser yenkambu emnyama. Ibonakala ngokungavumeli i-beam yokukhanya idlule into ngaphansi kokuhlolwa kusukela phansi kuya phezulu, kodwa ukushintsha indlela yokukhanya ukuze ihlehle ibheke entweni ehlolwayo, ukuze ukukhanya kokukhanyisa kungangeni ngokuqondile kulensi yenhloso, futhi isithombe esikhanyayo esakhiwe ukukhanya okukhanyayo noma okuphambanisayo ebusweni bento ehlolwayo kuyasetshenziswa. Ukulungiswa kokubhekwa kwensimu emnyama kuphakeme kakhulu kunokubuka kwensimu ekhanyayo, kuze kufike ku-0.02-0.004μm.
Izinzuzo:
Isebenza ekuhloleni amasampula abonisa ngale nangenambala, njengamaseli abukhoma.
Ithuthukisa imiphetho nezakhiwo ezinhle zesampula, ngaleyo ndlela ikhulise ukugqama.
Ububi:
Idinga ukusetha okuyinkimbinkimbi kanye nezisetshenziswa ezithile.
Kubandakanya ukulungisa ukuma kwesampula nomthombo wokukhanya ukuze uthole imiphumela emihle.
