I-10×50 binocular yangaphandle yokuqwala izintaba ama-binoculars angangeni manzi

Amapharamitha womkhiqizo

Ayini ama-binoculars?

Ama-binoculars, insimbi yokubona, ngokuvamile ebanjwa ngesandla, ukuze inikeze umbono okhulisiwe we-stereoscopic wezinto ezikude.Inezibonakude ezimbili ezifanayo, eyodwa ngeso ngalinye, ebekwe ohlakeni olulodwa.
1. Ukukhulisa
Ukukhulisa i-binocular inombolo ebhalwe ngo-x.Ngakho-ke uma i-binocular ithi 7x, kusho ukuthi ikhulisa isihloko izikhathi eziyisikhombisa.Isibonelo, inyoni eqhele ngamamitha ayi-1,000 izovela sengathi ikude ngamamitha ayi-100 njengokuyibona ngamehlo enyama.Ukukhulisa okungcono kakhulu kokusetshenziswa okuvamile kuphakathi kuka-7x no-12x, noma yini engalé futhi kuzoba nzima ukuphatha ngaphandle kwe-tripod.
2. I-Objective Lens Diameter
Ilensi yenhloso yileyo ephambana nocezu lwamehlo.Ubukhulu bale lens bubalulekile ngoba yibo obunquma inani lokukhanya elingena kuma-binoculars.Ngakho-ke ngezimo zokukhanya okuphansi, uthola izithombe ezingcono uma unelensi yomgomo omkhulu wobubanzi.Usayizi welensi ngo-mm uza ngemva kuka-x.Isilinganiso esingu-5 maqondana nokukhulisa silungile.Phakathi kwamalensi angu-8×25 kanye no-8×40, lena yakamuva idala isithombe esigqamile nesingcono esinobubanzi baso obukhulu.
3. Ikhwalithi yelensi, i-Coating
I-lens coating ibalulekile ngoba inciphisa inani lokukhanya eliboniswayo futhi ivumela inani eliphezulu lokukhanya ukuthi lingene.Ikhwalithi yelensi, ngakolunye uhlangothi, iqinisekisa ukuthi isithombe asiguquki futhi sinokugqama okungcono.Amalensi angcono kakhulu asebenza kangcono ezimeni eziphansi zokukhanya njengoba edlulisela ukukhanya okwengeziwe.Baphinde baqinisekise ukuthi imibala ayigezwanga noma ihlanekezelwe.Abasebenzisi abanezibuko kufanele babheke indawo yamehlo ephezulu.
4. Inkambu yokubuka/yokuphuma komfundi
I-FoW ibhekisela kububanzi bendawo ebonwa ezingilazini futhi ivezwe ngamadigri.Lapho inkambu yokubuka iba nkulu iyanda indawo oyibonayo.Umfundi ophumayo, ngakolunye uhlangothi, isithombe esakhiwe engxenyeni yamehlo ukuze umfundi wakho asibone.Ububanzi belensi ehlukaniswe ngokukhulisa bukunikeza umfundi ophumayo.Umfundi ophumayo ongu-7mm unikeza ukukhanya okukhulu esweni elivulekile futhi ilungele ukusetshenziswa lapho kuhwalala nezimo ezimnyama.
5. Isisindo Nokucindezeleka Kwamehlo
Umuntu kufanele acabangele isisindo se-binocular ngaphambi kokuyithenga.Cabanga uma ukusebenzisa ama-binoculars isikhathi eside kukukhathaza.Ngokufanayo, sebenzisa i-binocular futhi ubone ukuthi iyakhokhisa yini iso lakho.Nakuba kunzima ukusebenzisa ama-binoculars avamile isikhathi esingaphezu kwemizuzu embalwa ngesikhathi, lawo asezingeni eliphezulu awabangeli neze ukucindezelwa kwamehlo futhi angasetshenziswa amahora amade endaweni enwetshiwe uma kudingeka.
6. Ukuvimbela amanzi
Njengoba izibonakude ziyimikhiqizo yangaphandle, kubalulekile ukuthi zinezinga elithile lokuvimbela amanzi-lokhu kuvame ukuchazwa ngokuthi “WP”.Nakuba amamodeli avamile angahlala ngaphansi kwamanzi alinganiselwe amaminithi ambalwa, amamodeli asezingeni eliphezulu ashiywe engonakalisiwe ngisho nangemva kwamahora ambalwa ecwiliswe emanzini.

Izincomo zokukhetha isibonakude:

HAMBA
Bheka amamodeli ahlangene, angasindi anebanga elimaphakathi nendawo yokubuka.

UKUBUKELA INYONI NEMVELO
Idinga indawo ebanzi yokubuka nokukhulisa phakathi kuka-7x no-12x.

NGAPHANDLE
Bheka amamodeli aqinile anokuvimbela amanzi, ukuphatheka nokuqina.Ukukhulisa okukahle kuphakathi kuka-8x no-10x.Futhi bheka ububanzi benhloso enkulu kanye nokunamalensi okuhle ukuze kusebenze kahle ekuphumeni nasekushoniseni izimo zelanga.

MARINE
Bheka ukuvimbela amanzi ngenkundla ebanzi yokubuka kanye nokunciphisa ukudlidliza uma kungenzeka.

I-Astronomy
Ama-binoculars alungiswe nge-aberration anobubanzi obukhulu benhloso kanye nomfundi ophumayo angcono kakhulu.

ITHAYISHA/IMYUziyamu
Amamodeli ahlangene anokukhulisa okungu-4x kuya ku-10x angasebenza kahle ngenkathi ubuka imidlalo yasesiteji.Emamyuziyamu, kunconywa amamodeli angasindi anesikhulisi esiphansi nebanga lokugxila elingaphansi kwamamitha amabili ayanconywa.

EZEMIDLALO
Bheka indawo yokubuka ebanzi kanye nokukhulisa okungu-7x kuya ku-10x.Ukusebenza kwe-Zoom kungaba inzuzo eyengeziwe.

Umgomo wokusebenza:

Phakathi kwazo zonke izinsimbi zokukhanya, ngaphandle kwamakhamera, ama-binoculars athandwa kakhulu.Ivumela abantu ukuthi babuke imidlalo namakhonsathi ngokucophelela futhi yengeza ubumnandi obuningi.Ngaphezu kwalokho, izibonakude zezibonakude zinikeza umuzwa wokujula izibonakude ze-monocular ezingakwazi ukuwuthola.Isibonakude esidume kakhulu se-binocular sisebenzisa i-convex lens.Ngenxa yokuthi i-convex lens ihlehlisa isithombe phezulu naphansi futhi kwesokunxele nakwesokudla, kuyadingeka ukusebenzisa isethi yamaprism ukulungisa isithombe esihlanekezelwe.Ukukhanya kudlula kulawa maprism kusuka kulensi eyinhloso kuye kucezu lamehlo, okudinga ukuboniswa okune.Ngale ndlela, ukukhanya kuhamba ibanga elide ebangeni elifushane, ngakho umgqomo wesibonakude sezibonakude ungaba mfushane kakhulu kunalowo we- monocular telescope.Bangakwazi ukukhulisa okuhlosiwe okukude, ngakho ngabo, indawo ekude iyabonakala ngokucacile.Ngokungafani nezibonakude ze-monocular, izibonakude ze-binocular zinganikeza abasebenzisi umuzwa wokujula, okungukuthi, umphumela wokubuka.Lokhu kungenxa yokuthi lapho amehlo abantu ebuka isithombe esifanayo ema-engeli ahluke kancane, sizoveza umphumela onezinhlangothi ezintathu.

Siyakwamukela ukuzosibuza, siyabonga.
