Emehlweni Optical: kwebalingisi, idivayisi Ukukhetha mkhiqizo

Ukubona optical yidivayisi ekhethekile isetshenziselwa ukuthuthukisa ukunemba. Kuze kube manje, yena iyona engcono kunazo efana nayo. Iqiniso liwukuthi esimweni iyunithi iso izinkudla kwelinye ibanga, okuyinto kusiza ithiphu isikhali kwelitshe. Ukuyisebenzisela izikhali kwaqala ekhulwini le-17.

Lokhu emehlweni has a idivayisi kahle elula. Omunye izakhi eziyinhloko yidivayisi lens, esakhiwa lens amabili (kungaba khona ngaphezulu). izinga emehlweni encike ngqo kwi ubukhulu ingxenye: sikhulu kangakanani, ngcono emehlweni.

emehlweni Optical futhi sihlanganisa i okuhlanekezelwe isithombe uhlelo ukuguqulwa ngqo. Into ebalulekile iyona reticle, lapho isikhali kuhloswe umgomo. Itholakala indiza okufanayo isithombe kwelitshe, ngakho amehlo akubonayo kubo kahle ngokufanayo. Inama a kwasemuva, ukuze uma ngokudubula esithombeni amnyama futhi isakhiwo kungukuthi ahlanganisiwe. Ukuze isithombe bese reticle babhekwa yanda, izidingo ocular. Kuyinto uhlelo lens eziningana. Ngokuvamile, lapho unikezwa isango iraba, ezivikela ilele futhi elungisa iso emehlweni.

Ukuze izibhamu ungase pristrelyat'sya kanye yegridi inhlamvu hit iphuzu luqondane, le optical emehlweni indlela kuhlanganisa ukulungiswa evundla mpo.

Icala iyunithi senziwa ephezulu amandla izinto. amadivaysi banamuhla bangasebenzisa ukhulise isithombe kuze kube izikhathi ezingu-20. Akufanele ukuncika ngokumelene emehlweni telescopic ukuba iso ngesikhathi sokudubula, ngoba zonke isikhali has a ukubuya, ngisho emoyeni. Ngokuphathelene idivayisi fixing, kungase abe ukwesekwa ecaleni. Ubukhulu izesekeli ikakhulukazi ejwayelekile. Uma ukuphambuka kusukela ejwayelekile, futhi lapho, kuba abangelutho.

emehlweni Optical ukuze kungene umoya isibhamu kufanele kukhethwe ngokucophelela. Nakani isisindo ubukhulu tube futhi ubukhulu zedivayisi. Kusukela isikhali womoya ilula ngokwanele, akudingekile ukukhetha yokukhanya kakhulu. Ukunakwa nakho kulethwe ukulawula indlela ukulungisa, ububanzi we esitolo esidayisa of the eyepiece kanye kokukhulisa isithombe.

Ngokwemvelo, lokhu kusho idivayisi kufanele kube eyizingqabavu futhi amelana umonakalo lokukhanda. Futhi, emehlweni optical kumele ihlolwe zokumelana lokushisa omubi yobunzima. Kuyadingeka ukuba sihlole ngokucophelela umphathi wedivaysi indlela.

Yiqiniso, i-choice kwenziwa ngesisekelo salokho, ngayiphi injongo izosetshenziswa isiqu. Ngokwesibonelo, uma ufuna bacibishele ibanga sokudubula noma fixed target emoyeni sokuzingela, kungcono ukukhetha idivayisi olukwazi okwandisa isithombe izikhathi ezingaphezu kuka-4. Ikakhulukazi, lapho uphuma khona kufanele kube ebanzi ngokwanele.

Ngo inqubo Ukukhetha unethuba ukubheka ngokusebenzisa ububanzi entweni akude. Kufanele ubone eliphezulu, izithombe ezicacile ngaphandle kokuphazanyiswa. Kuyinto emehlweni kuwufanele olutholayo.
