Musika uyu unopa kabhuku kakakura kemabinoculars kwatinogona kuenzanisa nekusarudza mabhainokura akanakisa emhando dzakasiyana dzekushandisa dzinosanganisira kuona shiri, kukwira magwa, kudzika musasa, kuvhima, mitambo, makoniti, kutarisa, kuongorora nyeredzi, nezvimwe. Kudzidza sei kusarudza binoculars zvinogona kunetsa. Chero zvingave zvinodiwa nemushandisi, pane mabhainokura ane dhizaini chaiyo uye kuita kwechinangwa chawo. Kuti tisarudze mabhainokura akakodzera zvakanyanya, isu tinofanirwa kufunga nezve akasiyana siyana senge nharaunda, zvakati zvaunofarira, zviitiko, nezvimwe.
Nokuda kwechikonzero ichi, tichakumikidza chinyorwa ichi kukuudza kuti ungasarudza sei binoculars, maitiro avo uye kukosha.
Nzira yekusarudza mabinoculars
Kupenya uye kujeka kwemifananidzo inoonekwa kuburikidza nebinoculars, kunyanya, inotarirwa nemhando dzakasiyana-siyana. Kukudza, kurapwa lens uye chinangwa dhayamita zvimwe zvezvinhu zvinokanganisa kushanda kwemabinoculars.
Nekudaro, iyo yakakosha chiyero chebinoculars imhando yavo yemaziso. Celestron kukosha kwemari brand inopa emhando yepamusoro optics nekuda kwemagirazi akanyatsosarudzwa uye marapirwo emeso, maitiro ekugadzira chaiwo uye yakakura yemhando yekudzora.
Kuwedzera
Kukurisa ndiko mwero wekukudza kwechinhu chakaonekwa. Semuenzaniso, mu7x42 binoculars, nhamba yechinomwe inoreva "kukura kwechiridzwa." 7x mabinoculars anokudza zvinhu kanomwe zvichienderana neziso remunhu. Kukwidziridzwa kunokanganisa kupenya kwemufananidzo, saka iyo yakaderera kukwidziridzwa kwemabinoculars, iyo yakajeka chifananidzo chichava. Sezvo mutemo wega wega, kuwedzera kwekukura kunoguma mune yakaderedzwa ndima yekuona.
Chinangwa lens dhayamita
Iyo lens yechinangwa chebinoculars iri kumberi uye ine yakakura dhayamita. Iyo dhayamita (mu millimeters) yeimwe ye lenzi ndiyo yechipiri hunhu nhamba yemabhinokuri. Panyaya iyi, 7x42 binoculars ine 42mm dhayamita chinangwa. Iyo dhayamita yechinangwa lens inotaridza kugona kwebhainokura-kuunganidza, saka iyo yakakura dhayamita, inopenya uye yakanyanya kutetepa mufananidzo. Izvi zvinonyanya kukosha mumamiriro ekuderera uye usiku.
Izvi zvingaita kuti iwe ufunge kuti iyo yakakura dhayamita, zviri nani chiridzwa, asi muchokwadi, dhayamita ye lens pamwe chete nemamwe maparameter akadai semudzidzi wekubuda uye kushandiswa kwemabinoculars kunofanirwa kutariswa pakusarudza zvakanyanya kufanirwa paramita.
kubuda mudzidzi
Iyo "exit pupil" inogona kutsanangurwa sedhayamita, mumamilimita, yemwenje wemwenje unobuda kubva paziso remabinoculars. Iyo yakakura pupil yekubuda, inopenya mufananidzo unobuda. Kuve nemudzidzi mukuru wekubuda kunoita kuti zvive nyore kuona husiku uye muchiedza chakaderera. Muzvidzidzo zvemuchadenga, mwana wekubuda wemabinoculars anofanirwa kuenzana nemwero wekuti mudzidzi wemucherechedzi anowedzera kuwedzera paanenge achigadzirisa rima.
Kuti uverenge mudzidzi wekubuda, patsanura dhayamita yechinangwa neiyo magnification factor. Semuenzaniso, 7x42 binoculars ine 6mm yekubuda pupil.
Munda Wekuona (FOV)
Nzvimbo inoonekwa kuburikidza nebhainokura inonzi munda wekuona. Munda wekuona unowanzo kuratidzwa kunze kwebinoculars uye inopimwa mumadhigirii. Linear field of view inzvimbo inoonekwa pa1000 yards (915 metres), yakayerwa netsoka. Nzvimbo yakakura yekuona inoturikira kune nzvimbo yakakura inoonekwa kuburikidza nebhainokura.
Munda wekuona unobatana nekukwidziridzwa, kukwidziridzwa kwepamusoro, kudiki munda wekuona. Uyezve, nzvimbo yakakura yekuona inoguma mukuderedzwa kweziso / kureba kweziso. Nzvimbo yakakura yekuona inobatsira mumamiriro ezvinhu apo zvinhu zviri kufamba. Kuti uverenge mutsara wendima yekuona, wedzera kona yemunda wekuona ne 52,5. Semuenzaniso, mabinoculars ane munda wekuona 8o anovhara mutsara wemunda wekuona 420 tsoka (126 mamita).
Lenzi/chinhambwe cheziso
Iyi pfungwa inoreva chinhambwe (mumamilimita) icho mabhainokura anogona kupatsanurwa kubva paziso uchichengetedza nzvimbo yekuona yakagadzikana. Vanopfeka zviratidziro vachabatsirwa kubva kure kure.
Hurefu hwakaderera hwekutarisa
Ndiyo chinhambwe chiri pakati pemabhainokura uye chinhu chiri pedyo chinogona kutariswa uchichengetedza mufananidzo wakanaka.
Kupenya
Kugona kwebhainocular kutora uye kutumira chiedza chakakwana kuti chibudise mufananidzo wakajeka, wakajeka kunoratidza kupenya kwaro. Kupenya kwemabinoculars kunowedzerawo mutsauko pakati pemavara mumufananidzo wakaonekwa.
Relative Brightness Index (RBI), Twilight Index uye Relative Light Efficiency (RLE) ndizvo indexes inowanzoshandiswa mubinocular industry, asi kazhinji kacho hadzinzwisiswi kana kuti pfungwa dzisina zvadzinoreva.
Kupenya ipfungwa yekufunga nezve pakusarudza binoculars, asi haisi iyo inonyanya kukosha chinhu.
Kupenya kunoenderana nematanho akati wandei, kusanganisira dhayamita yechinangwa, kukwidziridzwa, rudzi uye kunaka kwegirazi rinoshandiswa, kugadzirisa kweiyo optics, uye rudzi rweprism inoshandiswa. Muzhinji, dhayamita hombe, yakaderera kana yepakati simba, yakazara-yakawanda-yakavharwa lenses inonyatsokodzera.
Prisms
Prisms mumabinoculars anoshandiswa kushandura mifananidzo uye kuuya mumagadzirirwo maviri: denga uye danda. Denga maprism akareruka uye anowedzera compact nedhizaini. Maprisms anonzi BK7 (borosilicate) uye BaK-4 (barium glass). Zvose zvakachipa uye zvinoshanda zvikuru. BaK-4 yekugadzira girazi ine yakakwira density (refractive index) iyo inobvisa zvachose chiedza chemukati, zvichikonzera mifananidzo yepamusoro-tsanangudzo.
musiyano
Contrast idhigirii iro zvinhu zviviri zvakapenya nerima zvinosiyana kubva kumashure kwemufananidzo. Musiyano wepamusoro unobatsira kuona zvinhu zvisina kusimba uye kuona zvakadzama. Kusiyanisa kunokonzerwa nekugadzirisa.
Iyo yakakwirira yekugadzirisa, iyo yakakwirira kusiyana. High quality optical processing inopa yakakwirira misiyano mifananidzo. Zvimwe zvinhu zvinokanganisa kusiyana kudhumhana, kuvhiringika kwemhepo, uye kunaka kwezvinangwa, maprism, uye zvidimbu zvemaziso.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve nzira yekusarudza binoculars uye zvaunofanira kufunga nezvazvo.
