Incazelo yesibonakude sezinkanyezi (ama-binoculars)
I-telescope yezinkanyezi noma ama-binocular ezinkanyezi iyithuluzi elibonakalayo elisetshenziselwa ukusiza iso ukubona izinto zasezulwini njengezinkanyezi, amaplanethi, amasathelayithi, njll. ngokucacile. Nakuba ubukhulu bezinto zasezulwini bukhulu kakhulu, ibanga phakathi kwezinto zasezulwini lide kakhulu kangangokuthi uma zibhekwa ngeso, izinto zasezulwini zibonakala zincane. I-telescope yezinkanyezi isebenza ukukhulisa isithombe sezinto zasezulwini ukuze zibonakale ngokucacile ngeso.
Izinhlobo zeTelescopes zezinkanyezi
Kunezinhlobo eziningana zama-telescope ezinkanyezi, okuhlanganisa ama-telescope acwebezelayo nabonisa ukukhanya. I-telescope ecwebezelayo, eyaziwa nangokuthi i-telescope ye-Keplerian, inama -lens amabili acwebezelayo abekwe kunoma yiliphi icala leshubhu. I-lens ecwebezelayo ekude kakhulu neso lomqaphi ibizwa ngokuthi i-lens eqondene, kanti i-lens ecwebezelayo eseduze neso ibizwa ngokuthi i-eyepiece. Ukuze ukhiqize isithombe esicacile sento yasezulwini, indawo engaphezulu yelensi eqondene kumele ibe nkulu. Ukwenza amalensi amakhulu ububanzi kunzima, ngakho-ke ama-telescope acwebezelayo awamakhulu kakhulu. Ama-telescope amakhulu kakhulu avame ukubonisa ukukhanya. Ama-telescope abonisa ukukhanya asebenzisa isibuko esicwebezelayo njengesibuko esiqondene.
Lesi sihloko sigxile engxoxweni mayelana nokushintshashintsha kwe-astronomical telescopes noma i-Kepler telescopes.
Indlela I-Refracting Astronomical Telescope Esebenza Ngayo
I-telescope yezinkanyezi ephendukayo inamalensi amabili acwebezelayo. Ilensi ecwebezelayo ekude kakhulu neso lomqaphi ibizwa ngokuthi ilensi eqondile, kanti ilensi ecwebezelayo eseduze neso lomqaphi ibizwa ngokuthi ilensi ye-eyepiece noma i-eyepiece. Ibanga lento libangela ukuthi i-eyepiece eyakhiwe phakathi kwento nelensi eqondile ibe yincane kakhulu. Ngakho-ke, ilensi eqondile isebenza ukuletha isithombe eduze nelensi ye-eyepiece ukuze i-eyepiece ibe nkulu. Ilensi ye-eyepiece isebenza ukukhulisa i-eye ukuze isithombe esakhiwe ku-retina sibe sikhulu.
Ibanga eliphakathi kwento kanye nelensi eqondiwe likude kakhulu futhi libhekwa njengelingenamkhawulo. Njengoba kuchaziwe esihlokweni selensi eqondile, uma into ikude kakhulu noma ingenamkhawulo, isithombe sisekugxilweni ngqo kwelensi eqondiwe. Isithombe singokoqobo, siguquliwe, futhi sincishisiwe. Ngenxa yokuthi isithombe sisekugxilweni kwelensi eqondiwe, ibanga eliphakathi kwesithombe nelensi eqondiwe (s ob ') lilingana nobude obuqondile belensi eqondiwe (f ob ).
Isithombe esikhiqizwe ilensi eqondile singokoqobo futhi ngenxa yalokho sibhekwa njengento ilensi ye-eyepiece. Uma iso lisesimweni esilinganiselwe, isithombe esakhiwe ilensi ye-eyepiece sikude kakhulu. Njengoba kuchaziwe esihlokweni isithombe selensi eqondile, ukuze isithombe esakhiwe yilensi ye-eyepiece siqhele kakhulu, isithombe sangempela esikhiqizwa yilensi eqondiwe futhi sibhekwe njengento ilensi ye-eyepiece, ngaphezu kokuba sendaweni egxile kulensi eqondiwe, kumele futhi sibe sendaweni egxile kulensi ye-eyepiece. Ngakho-ke kungaphethwa ngokuthi indawo egxile kulensi ezimbili eziqondiwe kanye nendawo yokuqala egxile kulensi ye-eyepiece kuyafana, njengoba kuboniswe esithombeni. Lapho ubude obugxile belensi ye-eyepiece (f)ok) kufana nebanga lesithombe sangempela kusuka kulensi ye-eyepiece (s)ok) khona-ke isithombe sokugcina esakhiwe ilensi ye-eyepiece sibonakala ngeso lengqondo, siguquliwe, sikhulisiwe futhi sikude kakhulu. Ibanga elingenamkhawulo lesithombe alisho ukuthi usayizi wesithombe awunamkhawulo.
Ngokusekelwe esithombeni kanye nencazelo engenhla, kungaphethwa ngokuthi ibanga eliphakathi kwelensi eqondiwe kanye nelensi ye-eyepiece ye-telescope elula = ubude be-telescope elula = ubude obugxile belensi eqondiwe (f ob ) + ubude obugxile belensi ye-eyepiece (f ok ).
Uma iso likwazi ukwamukela ngokugcwele, isithombe esakhiwe yilensi ye-eyepiece siseduze neso elivamile noma cishe ngamasentimitha angama-25 phambi ngelensi ye-eyepiece, lapho ibanga lesithombe (kulungile ' ) lincane kunobude obuqondile belensi ye-eyepiece (kulungile ' ). Ibanga lesithombe esakhiwe yilensi ye-eyepiece (kulungile ' ) lincane kunobude obuqondile belensi ye-eyepiece (kulungile ) ukuze isithombe sibe ngokoqobo futhi siguqulwe. Incazelo ephelele ingafundwa esihlokweni se- star telescope (binocular) formulas.
Ukukhuliswa Okuphelele Kweziteleskopu Zezinkanyezi
Ingabe ubukhulu besithombe sento ebonwa ngetheleskopu yezinkanyezi bukhulu uma bubhekwa yiso elinendawo encane yokuhlala noma iso elinendawo enkulu yokuhlala? Yikuphi okungcono ukusebenzisa njengelensi eqondile kanye ne-eyepiece, ilensi eqondile enobude obukhulu bokugxila noma ilensi eqondile enobude obuncane bokugxila? Le mibuzo ingaphendulwa ngemuva kokufunda ifomula yetheleskopu yezinkanyezi (ama-binoculars).
