Elithetha "zizibonakude 30x60 '? Indlela ukufumanisa ubuninzi zizibonakude

Ekuhambeni kwexesha lethu, ndibanqwenelela ukuthenga ezikumgangatho ophezulu zizibonakude amaqashiso mihla amathuba. Ukukhethwa iintlobo ngeentlobo ubuchule kbavelisi liphezulu kakhulu, kuquka kwiivenkile online. Kodwa kungcono ukukhetha umntu ukuba ukufanele kuwe technical parameters yaye kwangaxeshanye amalungiselelo ixabiso.

Le fowuni i kunokuba nzima Nngokobuchwepheshe, kwaye umlinganiselo umthengi ngamanye amaxesha kunzima ukuqonda iimpawu zayo. Umzekelo, elithetha "zizibonakude 30x60 '? Makhe zama ukufumana phandle.

Yintoni omabonakude

Ukufumana kukhetho, isigqibo kuwe ngokwaneleyo ukuba uyigcine, usebenzisa ukuba ifowuni kuphela ukukhanya, kodwa lakutshona ilanga, ukuba amalungiselelo kuguquka okulula, nto leyo mhlawumbi welula ubonwa ngamehlo? Ngothekelelo olufanayo, loo zizibonakude 30x60 ncomo yahluke kakhulu ngokuxhomekeke kwiimfuno yomnini.

Ngoko ke, kubalulekile ukuba isigqibo ukuba yintoni na ukuba uthenga le mveliso kunye neemeko apho baza ukuyisebenzisa.

Omabonakude kunokuba kumabala emidlalo kunye emkhosini, aselwandle okanye umbono ebusuku, kwakunye compact ezincinane - kuba akhoyo kule nkundla ngexesha lokhuphiswano. Okanye, phezu koko, ezinkulu, eyenzelwe ukuba izazi ngokuqaphela. Ngalinye iintlobo - iimpawu zazo. Ngamanye amaxesha zahluke kakhulu kakhulu. Ukwenza ukhetho elungileyo, aqhelane ezona ziphambili.

Yintoni ubuninzi?

Lo - enye yeempawu ezibalulekileyo kwisixhobo efana zizibonakude. Ubuninzi isixelela ukukwazi ukwandisa bume. Ukuba, umzekelo, umzimba wakhe - 8, entweni close-waphawula kakhulu uya kubonakala kumgama ukuya ku amaxesha 8 ngaphantsi kwe loo nto enyanisweni.

Zama ukuthenga isixhobo kunye ukukhulisa ephezulu kakhulu ngqiqweni. Eli nani kufuneka ezinxulumene iimeko kunye nendawo ukusetyenziswa zizibonakude. Okubonwayo endle wagqiba ukusebenzisa ubuchule kunye namanani ubuninzi-6 ukuya 8. zizibonakude Ukwanda amaxesha 8-10 - kumda apho kunokwenzeka ukuba ugcine nayo. Ukuba ngaphezulu - ukuthintela jitter, landile ukuya yokukhanya efanayo.

Omabonakude kunye nokwanda okukhulu (15-20 likriwa) zisetyenziswa kunye kwento apho ayinakutshintshwa ngokusebenzisa iadaptha ekhethekileyo okanye zombini. A bubunzima obuninzi kunye nemilinganiselo akunyanzelekanga ukuba banxibe elide yaye kwiimeko ezininzi akukho mfuneko, ingakumbi xa ngokutsha intsonkothile imiqobo emininzi.

Ifumaneka onobuhle ubuninzi eziguquguqukayo (Pancratic). The degree of Ukwanda kwezi kwatshintsha ngesandla, ngathi se lokushicilela. Kodwa kwakungenxa yobumbaxa bhetele indlela idivayisi ayabiza kakhulu.

Elithetha "zizibonakude 30x60", okanye ukuthetha malunga ubukhulu lens

Ukumakishwa binocular liquka nawuphi na ubukhulu bepali lens yayo phambi ilens, leyo iqhutywa ngoko nangoko emva ratio isibonisi. Umzekelo, elithetha "zizibonakude 30x60 '? La manani ngoko decoded: 30x - figure ubuninzi, 60 - ubungakanani ilens ubukhulu mm.

Ukususela sangqa kumfanekiso lens umgangatho ixhomekeke. Ukongeza, kwagqitywa ubungakanani bokukhanya eqokelelwe lens zizibonakude - nguwo ebanzi, le ubukhulu enkulu. iimeko jikelele efake zizibonakude ingqalelo enombhalo 6x30, 7x35, okanye ubuncinane 8x42. Ukuba uceba emini ukuba agcine kwindalo, ndakubona ukuba izinto ezithile ezikude, uthabathe ifowuni kunye nokwanda-8 okanye 10-emhlambini, ilens sangqa mm-30 ukuya kuma-50. Kodwa ngongcwalazi, ukuba asiphumeleli kakhulu ngenxa yokuba ukukhanya ngaphantsi bangene lens.

Le zizibonakude kakhulu ababukeli xa iziganeko zemidlalo - i (uguqulelo epokothweni) ezincinane parameters malunga 8h24, ukuba awunankinga kwisicwangciso jikelele.

Ukuba ukukhanya akwanelanga

Xa iimeko zokukhanya ephantsi (ukutshona kwelanga okanye isifingo) kumele bakhetha isixhobo enkulu ubukhulu lens okanye umbingelelo ubuninzi. Umlinganiselo kangangoko inokuba 7x50 okanye 7h42.

Iqela eyahlukileyo - ekuthiwa-ngobusuku-iiglasi - active and passive izixhobo ngombono ebusuku. Xa lens nje babonelelwa ukutyabeka multilayer ukuba khipha ilitha. Zisetyenziswa ekho nje ukhanyiso zisezantsi (umz, inyanga). Zizixhobo esebenzayo kwakhona isebenze ebumnyameni ngokupheleleyo, njengoko infrared lisetyenziswa kubo. Thabatha zabo - uxhomekeko umbane.

Lovers ukuba ukufunda izinto yesiqalo (umzekelo, cinga imizila kumphezulu kwenyanga) kufuneka zizibonakude namandla ngokwaneleyo, kunye nokwanda ubuncinane 20x. Ukuze ufumane umhlobo iinkcukacha ngakumbi isibhakabhaka busuku bekumi ngeenkwenkwezi engahlawulwayo Kulungile teleskopu, nto kulo mzekelo akuyi indawo nkqu zizibonakude kakhulu.

Yintoni ikona ukubukela?

Abone ngayo (okanye intsimi) - elinye kunazo. Eli xabiso imele ububanzi degree of network. Le parameter bomzimba ukunyuka kuxhomekeke - zizibonakude enikwe abe 'uluvo' encinane.

Ukuba ukubukela enkulu engile zizibonakude ekubhekiselelwe ngokuba ibanzi-engile (okanye widefield). Kulula ukuthatha ezintabeni, ukuba hlengisa ngcono ngokwabo esithubeni.

Amaxesha amaninzi icandelo esebenzayo kubonakaliswa engile hayi hlelo kunye nobubanzi umgca okanye indawo, leyo enokuthi ibonwe uluhlu standard of 1000 m.

Ezinye iinkalo omabonakude

Ubukhulu be umfundi yokuphuma ibizwa ngokuba QUOTIENT le sangqa umfundi yokungena kwi ratio ubukhulu. Oko kukuthi, kunye zizibonakude 6x30 ukumakisha eli nani - 5. Inani egqibeleleyo, kulo mzekelo - malunga nama-7 mm (ubungakanani umfundi kwabantu).

Elithetha "zizibonakude 30x60" kule meko? Isibakala sokuba ubungakanani umfundi yokuphuma kwi zokuphawula loo 2. iiglasi enjalo asihambelani uphononongo oluthatha ixesha elide kakhulu kunye Izibane elungileyo kwaye siya kukhangelana amehlo ukukhathala uhlobo. Ukuba ukukhanyisa ulihlwempu, okanye ukubheka phambili, eli nani kufuneka zibe-5 ubuncinane, ekukhethwa 7 okanye ngaphezulu.

Enye indlela - umngxuma "ophetheyo" yomfanekiso ukukhanya. She - ngokomlinganiselo ngqo kwi sangqa umfundi yokuphuma. inani Abstract, nezibonakalisa ngayo, ilingana kwisikweri se ubukhulu bayo. kunqweneleka ukuba eli zinga kungekho ngaphantsi kwe-25 phantsi kweemeko ukukhanya kuyehla.

into elandelayo - focus. Libalulekileyo, oko - yindlela yendalo ekuloleni ngokukhawuleza. I isilawuli ngoko kubhaliwe kufuphi njengehenjisi kokuxhuma umbhobho. Izibuko Kuyancomeka ukuba zizibonakude kunye hlengiso diopter.

Yiyiphi enye into ebalulekileyo kukuba

Abanye, hayi iimpawu zehlabathi kangaka omabonakude, kunjalo, kudlala indima ebalulekileyo ekukhetheni yakhe. Ubunzulu endle kuthiwa ixabiso abangakwaziyo ukuya into lokuqaphela, nto leyo efunekayo ukutshintsha ugxininiso entliziyweni. It uphantsi, kokukhona ke ubuninzi kwefowuni.

Omabonakude eyodwa (binocular) luphawu ezingundoqo iliso uphawu yabantu, nto leyo eyenza kube lula ukubona izinto imali nexesha. Oku luncedo phambi okanye monocular Array. Kodwa ke umgangatho leyo luncedo entsimini, aphazamise kwezinye iimeko. Ngoko ke, umzekelo, kwi iindondo opera inciphisiwe.

Ngokutsho inkqubo woqondo zizibonakude lens zezi (theatre, ungowaseGalili) kunye prismatic (okanye field). Kulo wokuqala - imbobo ratio elungileyo, umfanekiso live, ukonyuka encinane, kunye nebala elimxinwa umbono. Okwesibini, prisms asetyenziswa, iguqulela umfanekiso zocaphulo ifunyenwe ilens in njengesiqhelo. Oku kunciphisa ubude kunye binocular ukubukela engile ukunyuka.

Elubala into ibizwa ngokuba isixhobo ubuchule Kwathi reyi ukukhanya wavakalisa amaqhekeza. Ngokomzekelo, xa 40% yokulahlekelwa ukukhanya, le lomlingani ilingana no 0.6. ixabiso layo eliphezulu - le yunithi.

Njani na umzimba omabonakude

main inzuzo yayo - amandla. kwizinga Shockproof izindlu rubberised inikezelwa, ngalo kwakhona kolu ukuthembeka ngexesha ugcina izandla kunye nokumelana ukufuma imozulu ifumile.

omabonakude waterproof Modern ziyatywinwa ukuze kubekho ixesha elithile ngaphantsi kwamanzi ukuya kubunzulu iimitha ezi-5 ngaphandle umonakalo ngokwayo. Ezi lens biyela fogging, ugcwalisa isikhala phakathi kwabo initrogen. zibalulekile beentaba, abazingeli, zemvelo ezi mpawu. omabonakude Rangefinder ne ngumphandi imidlalo, isixhobo zokuqhubela kunye andigqibe matte - abalandeli ukubukela izilwanyana.

Ezinye iimpawu ezingekho semgangathweni yezixhobo azimeleyo afana somfanekiso, a laser uluhlu njengevyufayinda okanye ikhampasi eyakhelwe-ngaphakathi ukwandisa kakhulu iindleko kunye zizibonakude bamkelekile kuphela xa kuyimfuneko. Gqiba ngokwakho - kufuneka nokuba ezifana zizibonakude rangefinder ukuba niyavuma ukuhlawula eyongezelelweyo olu khetho.
