I-binoculars yezinkanyezi zokubheka

Ama-binoculars akuyona nje isisombululo esikahle sokuqapha izinto ezingaphansi komhlaba, kodwa ngesinqumo esanele ngokwanele ithuluzi eliphumelelayo lokusetshenziswa kwezinkanyezi. Kulesi sihloko, ake sikhulume ngezindiza zezinkanyezi, izici zokuzikhethela nokusebenza kwazo.

Izinzuzo

Ama-binoculars okubhekwa kwezinkanyezi ahlukaniswa yizinzuzo ezilandelayo:

1. Kungenzeka ukusebenzisa kokubili amehlo ukugcina imizimba yasezulwini. Ngesikhathi i-telescope ikuvumela ukuba ubuke izinto ngokusebenzisa lens eyodwa.
2. Ukuthola isithombe se-3D, ngenxa yomthelela othize we-stereo.
3. Inkambu ebanzi yokubuka yenza amabhayisikobho ezinkanyezi ithuluzi elihle lokucubungula ama-comet akhanyayo, amasimu ezinkanyezi, ama-asteroids, njll.
4. Kuphumelela uma kudingekile ukwakha uhlelo olucacile jikelele lwezinkanyezi.
5. Ama-binoculars asezinkanyezi anikezela isithombe esiqondile. Ama-telescopes akha isibuko, isithombe esiphenduliwe.

Ukuphindaphindiwe

Kunezinhlobo eziningana zezinkinobho zezinkanyezi, ezisetshenziswa kabanzi yizinkanyezi ze-amateur. Okuvamile, ukuhluka kwesabelomali kuyisibonelo ngokuphindaphindiwe kwe-8x40. Ama-binoculars ezinjalo zezinkanyezi anona i-angle yokubukwa kakhulu kunazo zonke. Ukusebenza kwalo kwenza kube lula ukuthola izinto ezaziwayo esibhakabhakeni. Amamodeli wokuphindaphindana amancane alula kunabo abalingani bawo abakhulu. Ngakho-ke, kulula ukusebenza njengedivayisi yokubheka ngesandla.

Ama-binoculars anenqwaba ye-7x50 anayo yonke inzuzo yama -lens amaningi-angle. Noma kunjalo, ukwakheka kwesithombe esicacile lapha kuxhomeke ekukhanyeni kwendawo esungezile. Ngakho-ke, le nketho ayiphumelelanga kakhulu uma isetshenziswe kusihlwa, ekukhanyeni kwedolobha elikhanyayo. Ngesikhathi esifanayo, ukuphindaphindwa okuphezulu kwenza kube lula ukucubungula ama-nebulae ama-gaseous, iqoqo lezinkanyezi.

Amadivaysi ane-10x50 amaningi ama-binoculars amakhulu kunazo zonke esesigaba samadivayisi amateur. Zihlukile emkhakheni omncane wokubukwa, okwenza kube lula ukuhlola ngokuningiliziwe izakhi zezinkanyezi eziseduze noMhlaba, ikakhulukazi iNyanga. Noma kunjalo, ubukhulu obunomthelela abuvumeli ukugcina amadivayisi anjalo ezandleni ezenza kahle. Ngakho-ke, ukuze usebenzise kalula i-binoculars yezinkanyezi zokuphindaphinda okukhulu, kutuswa ukuthenga i-tripod ekhethekile.

I-Collimation

Lo mqondo uyim parameter ebalulekile uma ukhetha noma yiziphi i-binoculars. I-collimation yedivaysi ibonisa ukuthi izingxenye zayo zemi mechanical and optical zihambisana nomunye nomunye. Ukuhlola ikhwalithi yokulungiselelwa kwepharamitha, kwanele ukubuka kokubili ama-eyepieces ama-binoculars. Ngesikhathi esifanayo, ukugxila okusheshayo ezintweni ezitholakala kumabili amabanga amancane nezide kufanele zenzeke. Ukubheka ema-binoculars ama-collimated kahle kuzoholela ekukhuphukeni okukhulu kwamehlo.

Izici zamamodeli ahlukene

I-binoculars yezinkanyezi ingaba nokugqoka ama-lens ezinemibala enemibala. Noma kunjalo, amagobolondo anjalo akhangayo anganciphisa ikhwalithi yesithombe esilandelayo. Enye into - imikhiqizo enezihlungi ze-orange. Zikuhle kangakanani lezi zinobuchopho zezinkanyezi? Impendulo yomsebenzisi ibonisa ukuthuthukiswa esithombeni uma ubheka izinto ngokusebenzisa imikhiqizo enezilonda zalo ezinalo hlobo lokufaka.

Ezingqungqutheleni ezibiza kakhulu zezinkanyezi, kunikezwa i-angular scale. Ngesizo salo, ungakwazi ukukala amabanga aqondile nendawo ephakathi kwamanye amazwe. Kodwa-ke, ukuba khona kwekhetho akusho ukuthi lesi sikali sizohlukaniswa ngokucacile ebumnyameni. Ngakho-ke, ngaphambi kokuthenga i-pair of binoculars enjalo kuyadingeka ukuba uyivivinye ngokwenza, okungenani ngezimo zobusuku.

Ama-lens ezinkanyezi ezithile zezinkanyezi ziqukethe i-electron beam cover. Ngesinye isikhathi, ubuchwepheshe buvinjelwe umthuthukisi owaziwa ngokucacile - i-Fujifilm. Lapha, ubuso be-lens bubhekwa ukwelashwa okukhethekile, lapho okudlula khona okudlula cishe ama-95% wokukhanya. Ngakho, izinto ezikhonjisiwe zikhanya kakhulu ngangokunokwenzeka. Ngesikhathi esifanayo, isithombe esiphezulu sichazwa.

I-binoculars yezinkanyezi ingaqukatha ama-optics aphansi. Ukusetshenziswa kobuchwepheshe ekuthuthukiseni idivayisi kuboniswa yizimpawu ze-ED. Ukufakwa kwama-optics anjalo kwenza kube lula ukugwema ukubukeka kokuphazamiseka kombala okwenziwe emaleni ngenxa yokusabalalisa kwemisebe ekhanyayo kuboniswa emzimbeni ngamunye. Ukuba khona kwama-lens aphansi-ukusabalalisa kuyisibonakaliso somkhiqizo ophezulu.

Abakhiqizi

Phakathi kwezinto zokukhiqiza ezifuywayo ze-binoculars zezinkanyezi, kufanelekile ukukhuluma ngemikhiqizo ye-Kazan Optical-Mechanical Enterprise. Lapha, ikakhulukazi ama-binoculars ezempi akhiqizwa, aqukethe ukumaka okukhethekile "BSh". Amadivayisi anjalo anegridi yegoniometer. I-Optics yekhwalithi elihle kakhulu efakwe kubo, okwenza kube nesisombululo esihle kakhulu sesabelomali sokugcina imizimba yasezulwini.

Ngezinhloso zezinkanyezi, ama-binoculars asekhaya asekhaya "Yukon" kusukela ochungechungeni olumakwe Pro lingasetshenziswa futhi. Imikhiqizo yalesi sigaba inezihlungi zokukhanyisa i-orange kanye negridi yefriji yefrijini. Kunezimbozo ezinamathele ezenza njengesikrini ukucima ama-glare avela ezikhanyeni zecala.

Ama-binoculars angenayo ama-binoculars angenisa amazwe anjengoba: Canon, Nikon, Pentax, Fujifilm. Ngisho nemikhiqizo eshibhile esivela kwenye yalezi abakhiqizi yenza kube lula ukucabangela ngokuningiliziwe imizimba eminingi yasezulwini kunama-binoculars avamile.

Ekuphethweni

Ukubamba iqhaza, ngingathanda ukunikeza iseluleko kubasebenzisi abahlose ukuthenga amabhayisikili ezinkanyezi. Okokuqala, ungathengi idivayisi esitolo. Njengomthetho, amadivayisi anjalo anegobolondo elikhangayo kuphela. Kodwa-ke, ngokuzikhandla banamathengi angenangqondo ngaphezu kwesimiso esibi sokuqapha izinto ezikude.

Uma ukhetha ama-binoculars wezinkanyezi kunconywa ukugwema ukukhiqizwa kwabakhiqizi abangaziwa, ikakhulukazi imikhiqizo yaseChina. Ngaphambi kokuthenga kuyadingeka futhi ukubonisana nomuntu onolwazi, buka ukubuyekezwa kwezithombe ezithakazelisayo, ezilungiselelwe abasebenzisi abanolwazi.
