Lub telescope yog ib qho khoom siv kho qhov muag pom kev siv los saib xyuas cov khoom nyob deb, uas tuaj yeem nthuav dav lub kaum sab xis qhib me me ntawm cov khoom nyob deb raws li qee qhov kev nthuav dav, kom nws muaj lub kaum sab xis qhib loj hauv qhov chaw duab, kom cov khoom tsis tuaj yeem ua. pom lossis txawv ntawm qhov muag liab qab ua kom pom tseeb thiab paub qhov txawv. Yog li ntawd, telescopes yog indispensable cuab yeej nyob rau hauv astronomy thiab kev soj ntsuam hauv av. Nws yog ib qho kev kho qhov muag uas siv lub hom phiaj lens thiab eyepieces kom qhov teeb meem nyob rau tib lub sij hawm beam tseem emission nyob rau hauv parallel. Raws li lub hauv paus ntsiab lus ntawm telescopes, nws yog feem ntau muab faib ua peb hom. Ib qho cuab yeej uas sau cov hluav taws xob nthwv dej los saib xyuas cov hluav taws xob hluav taws xob ntawm cov khoom nyob deb, hu ua xov tooj cua telescope, hauv lub neej niaj hnub, telescopes feem ntau yog xa mus rau optical telescopes, tab sis nyob rau hauv niaj hnub astronomy, astronomical telescopes muaj xws li xov tooj cua telescopes, infrared telescopes, X-ray thiab gamma. tsom iav tsom iav. Lub tswv yim ntawm astronomical telescopes txuas ntxiv mus rau gravitational nthwv dej, cosmic rays, thiab tsaus teeb meem.
Optical telescopes hauv lub neej niaj hnub tseem hu ua "clairvoyant mirrors". Nws feem ntau suav nrog amateur astronomical telescopes, theatre telescopes thiab tub rog binoculars.
Feem ntau siv binoculars kuj yuav tsum tau ntxiv ib tug prism system rau lub hom phiaj ntawm txo lub ntim thiab flipping lub inverted duab, thiab lub prism system yuav muab faib mus rau hauv lub Roof Prism system (uas yog, lub Smit-Beehan Roof Ridge Prism System) thiab cov Paul Prism System (Porro Prism) (tseem hu ua Pro-Prism System) raws li cov qauv ntawm cov qauv, thiab cov hauv paus ntsiab lus thiab kev siv ntawm ob lub tshuab zoo sib xws.
Lub koob yees duab me me rau kev siv tus kheej yuav tsum tsis txhob siv qhov loj loj, feem ntau 3 ~ 12 zaug yog qhov tsim nyog, thaum qhov kev nthuav dav loj dhau, qhov kev pom tseeb yuav dhau los ua neeg tsis zoo, thiab lub zog yog qhov hnyav, ntau dua 12 npaug ntawm lub koob yees duab feem ntau siv tripods. thiab lwm yam kev kho.
