Amalensi e-Plano-Concave Umdwebo we-PDF

Amalensi okukhanya ayizingxenye ezibonakalayo ezibonakalayo ezinezindawo ezigobile ezingaguqula ukukhanya futhi zigxile ekukhanyeni. Asetshenziswa kabanzi ezinhlelweni ezahlukene zokukhanya ukulawula imisebe yokukhanya, ukulungisa umbono, ukukhulisa izinto, nokwenza izithombe. Amalensi ayizinto ezibalulekile kumakhamera, kumatheleskopu, kumamicroscope, kumazibuko, kumaphrojektha, nakwamanye amadivayisi amaningi okukhanya.

Kunezinhlobo ezimbili eziyinhloko zamalensi:

Amalensi ahlanganisiwe (noma ahlanganayo): La malensi ajiyile maphakathi kunasemaphethelweni, futhi ahlangana nemisebe yokukhanya ehambisanayo edlula kuwo iye endaweni egxile ngakolunye uhlangothi lwelensi. Amalensi aqondile avame ukusetshenziswa ekukhuliseni izibuko, amakhamera, kanye nezibuko zamehlo ukuze kulungiswe ukubona kude.

Amalensi aguqukile (noma ahlukanisiwe): La malensi mancane maphakathi kunasemaphethelweni, futhi abangela ukuthi imisebe yokukhanya ehambisanayo edlula kuwo ihlukane sengathi ivela endaweni ebonakalayo ohlangothini olufanayo lwelensi. Amalensi aguquliwe avame ukusetshenziswa ekulungiseni ukubona eduze.

Amalensi aklanywa ngokusekelwe kubude bawo obuqondile, okuyibanga elisuka kulensi kuya endaweni eqondile. Ubude obuqondile bunquma izinga lokugoba kokukhanya kanye nokwakheka kwesithombe okuphumelayo.

Amanye amagama abalulekile ahlobene nama-lens optical afaka:

Iphuzu lokugxila: Iphuzu lapho imisebe yokukhanya ihlangana khona noma ibonakala sengathi iyahlukana ngemva kokudlula kulensi. Kulensi eqondile, yilapho imisebe ehambisanayo ihlangana khona. Kulensi eqondile, yiphuzu lapho imisebe ehlukene ibonakala sengathi ivela khona.

Ubude be-focal: Ibanga eliphakathi kwelensi nendawo egxile kuyo. Kuyipharamitha ebalulekile echaza amandla elensi kanye nosayizi wesithombe esakhiwe.

Imbobo: Ububanzi belensi obuvumela ukukhanya ukuthi kudlule. Imbobo enkulu ivumela ukukhanya okwengeziwe ukuthi kudlule, okuholela esithombeni esikhanyayo.

I-axis ebonakalayo: Umugqa ophakathi odlula phakathi kwelensi uqonde phezulu ezindaweni zayo.

Amandla ngelensi: Njengoba ilinganiswa ngama-diopters (D), amandla elensi abonisa ikhono lokubuyisa lelensi. Amalensi aqondile anamandla amahle, kuyilapho amalensi aqondile enamandla amabi.

Amalensi okubona ashintshe imikhakha ehlukahlukene, kusukela kusayensi yezinkanyezi kuya kwezokwelapha, ngokusivumela ukuthi sibone izinto ezikude, silungise izinkinga zokubona, futhi senze izithombe nezilinganiso ezinembile. Ayaqhubeka nokudlala indima ebalulekile ekuthuthukiseni ubuchwepheshe kanye nokuhlola kwesayensi.
