Ukuqonda Ama-Microscope
isibonakhulu iyithuluzi lokukhanya elisetshenziselwa ukusiza iso ukuthi libone izinto ezincane kakhulu ngokucacile, lapho lezi zinto ezincane kakhulu kunzima ukuzibona ngqo kusetshenziswa imakroskopu. mata noma impisi.
Kunezinhlobo ezimbili zama-microscope, okungukuthi imakroskopu yokukhanya dan imakroskopu ye-electronLesi sihloko sixoxa ngama-microscope okukhanya nokuthi asebenza kanjani maqondana nesihloko i-geometric optics kufaka phakathi ukufiphaza ukukhanya, ukwakheka kwesithunzi kanye nokukhulisa isithunzi sento kusetshenziswa ilensi.
Ngaphambi kokufunda lesi sihloko, kungaba ngumqondo omuhle ukuthi uqale uhlole izibuyekezo eziphathelene nalokhu ingilazi yokukhulisa noma i-loupe ukuze ukwazi ukuqonda lesi sihloko kalula futhi ngokushesha.
Indlela I-Microscope Esebenza Ngayo
I-microscope elula ekhanyayo inamalensi amabili acwebezelayo. Ilensi ecwebezelayo eseduze nento ebonwayo ibizwa ngokuthi... ilensi eqondileIlensi eqondile eseduze neso lomqaphi ibizwa ngokuthi ilensi yeso noma ilensi yeso.
Izinto zincane kakhulu ngobukhulu, ngakho-ke noma ngabe zibonwa kude eduze nendawo yeso elivamile Ebangeni elingama-25 cm, i-engeli eyakhiwe phakathi kweso nento incane kakhulu. Ngakho-ke, ilensi eqondiwe isebenzela ukukhulisa isithombe sento futhi yandise i-engeli ephakathi kweso nesithombe. Isithombe esikhiqizwe ilensi eqondiwe kumele sibe ngokoqobo ukuze sibonakale ngelensi ye-eyepiece. Njengoba kuxoxwe ngakho esihlokweni isithombe selensi eqondile, ukuze isithombe esikhiqizwe ilensi eqondile sibe ngokoqobo, ibanga (ama) lento kumele libe likhulu kunobude bokugxila. Ngokufanayo, ukuze isithombe sibe sikhulu kunento, ibanga lento kumele libe seduze nendawo yokugxila yelensi eqondiwe.
Isithombe esikhiqizwe ilensi eqondile singokoqobo ukuze isithombe singabhekwa njengento yiso. ilensi yesithombe samehloUmsebenzi welensi ye-eyepiece ukukhulisa isithombe sangempela esikhiqizwe yilensi eqondile ukuze sikhule. Ngakho-ke, ilensi ye-eyepiece ilensi eqondile, njengoba kuchaziwe esihlokweni. isithombe selensi eqondile, ukuze isithombe esikhiqizwe ilensi yeso sibe sikhulu kakhulu futhi siqonde phezulu, isithombe kumele sibe ngokoqobo.
Ukukhulisa Okuphelele Kwe-Microscope
Ingabe isithombe sento ebonwa nge-microscope sikhulu uma sibonwa yiso elinendawo encane noma iso elinendawo enkulu? Yikuphi okungcono ongakusebenzisa njengelensi ye-objective kanye ne-eyepiece, ilensi ye-convex enobude obukhulu be-focal noma ilensi ye-convex enobude obuncane be-focal? Le mibuzo ingaphendulwa ngemva kokutadisha ifomula yesibonakhulu.
