Isingeniso sengilazi yokukhulisa, isikhulisi

Uma ufuna ukwazi ukuthi yini aingilazi yokukhulisaukuthi, sicela ufunde okulandelayo:

Ingilazi yokukhulisaiyithuluzi elilula elibonakalayo elisetshenziswa ukubuka imininingwane emincane yento.Iyilensi eguqukayo enobude bokugxila obuncane kakhulu kunebanga elikhanyayo leso.Usayizi wento efanekiselwa ku-retina yomuntu ulingana ne-engeli yento esesweni (i-engeli yokubuka).

Isingeniso esifushane:
Uma i-engeli yokubuka ibe nkulu, iba nkulu isithombe, nokukwazi ukuhlukanisa imininingwane yento.Ukusondela entweni kungakhuphula i-engeli yokubuka, kodwa kunqunyelwe ikhono lokugxila leso.Sebenzisa aingilazi yokukhulisaukulenza libe seduze neso, nokubeka into ngaphakathi kokugxila kwayo ukuze yakhe isithombe esiqondile esibonakalayo.Ingilazi yokukhulisa isetshenziselwa ukukhulisa i-engeli yokubuka.Ngokomlando, kuthiwa ukusetshenziswa kwengilazi yokukhulisa izingane kwahlongozwa ugrosstest, umbhishobhi waseNgilandi ekhulwini le-13.

Emuva eminyakeni eyinkulungwane edlule, abantu baba namakristalu abonisa ngale noma amatshe ayigugu abonisa ngale ku-“amalensi", engakhulisa izithombe.Yaziwa nangokuthi i-convex lens.

Isimiso:
Ukuze ubone into encane noma imininingwane yento ngokucacile, kuyadingeka ukusondeza into eduze neso, okungase kwandise i-angle yokubuka futhi kwakhiwe isithombe esikhulu sangempela ku-retina.Kodwa lapho into iseduze kakhulu neso, ayikwazi ukubona kahle.Ngamanye amazwi, ukuqaphela, akufanele nje wenze into ibe ne-engeli enkulu ngokwanele esweni, kodwa futhi uthathe ibanga elifanele.Ngokusobala, emehlweni, lezi zimfuneko ezimbili zikhawulelana.Uma i-convex lens ilungiselelwe phambi kwamehlo, le nkinga ingaxazululeka.I-Convex lens iyingilazi yokukhulisa elula kunazo zonke.Kuyithuluzi elilula lokubona elisiza iso ukubona izinto ezincane noma imininingwane.Ukuthatha ilensi eyi-convex njengesibonelo, amandla ayo okukhulisa abalwa.Beka into engu-PQ phakathi kokugxilwa kwento yelensi L kanye nelensi futhi uyenze ibe seduze nalapho kugxilwe khona, ukuze into yakhe isithombe esibonakalayo esinwetshiwe u-p ′ Q 'ngelensi.Uma ubude bendawo yesithombe esiyisikwele selensi eyi-convex bungu-10cm, amandla okukhulisa wengilazi yokukhulisa eyenziwe ilensi izikhathi ezingu-2.5, abhalwe ngokuthi 2.5 ×.Uma sicabangela kuphela amandla okukhulisa, ubude bokugxila kufanele bube bufushane, futhi kubonakala sengathi noma yimaphi amandla amakhulu okukhulisa angatholakala.Kodwa-ke, ngenxa yokuba khona kokuphazamiseka, amandla okukhulisa ngokuvamile angaba ngu-3 ×. Uma inhlanganiselaingilazi yokukhulisa(okufana ne-eyepiece) isetshenziswa, i-aberration ingancishiswa futhi ukukhuliswa kungafinyelela ku-20 ×.

Indlela yokusebenzisa:
Indlela yokubona 1: vumela ingilazi yokukhulisa isondele entweni ebonwayo, into ebhekiwe ayinyakazi, futhi ibanga phakathi kweso lomuntu nento ebhekiwe alishintshi, bese uhambisa ingilazi yokukhulisa ngesandla iye phambili naphambili phakathi into kanye neso lomuntu kuze kube yilapho isithombe sikhulu futhi sicacile.

Indlela yokubona 2: ingilazi yokukhulisa izoba seduze kwamehlo ngangokunokwenzeka.Gcina ingilazi yokukhulisa inganyakazi bese uhambisa into kuze kube yilapho isithombe sikhulu futhi sicacile.

Injongo eyinhloko:
Isetshenziselwa ukubuka amaphepha kanye nezitolo zokunyathelisa zamaphepha, amathikithi, izitembu, izinhlamvu zemali namakhadi kwezezimali, intela, i-philately kanye nezimboni ze-electronic.Ingakwazi ukubona ngokunembile nangokushesha imali engamaphepha mbumbulu enokulungiswa okuphezulu.Uma ukutholwa kokukhanya okunsomi kungalungile, sebenzisa ithuluzi.

Ingabonakala ngokunembile.I-RMB yangempela inemigqa ecacile nemigqa ehambisanayo ngaphansi kwesibonakhulu.Amaphethini wamaphepha omgunyathi ngokuvamile akhiwa amachashazi, imigqa engaqhubeki, umbala okhanyayo, ongaqondakali futhi ongenawo umuzwa wezinhlangothi ezintathu.

Isetshenziswa embonini yobucwebe, ingakwazi ukubona ukwakheka kwangaphakathi kwamatshe ayigugu, ukuhlelwa kwamangqamuzana ahlukene, futhi ihlaziye futhi ikhombe amasampula ensimbi nezinsalela zamasiko.

Embonini yokunyathelisa, ingasetshenziselwa ipuleti elihle, ukulungisa umbala, ukubhekwa kwechashazi nonqenqema, futhi ingakala ngokunembile inombolo yemeshi, usayizi wechashazi, iphutha lokuphrinta ngokweqile, njll.

Isetshenziswa embonini yendwangu, ingabuka futhi ihlaziye i-fiber yendwangu kanye ne-warp ne-weft density.

Isetshenziswa embonini ye-elekthronikhi ukubuka imigqa yomzila kanye nekhwalithi yebhodi lebhodi le-copper platinum ephrintiwe.

Isetshenziselwa ukubuka nokucwaninga ngamagciwane nezinambuzane kwezolimo, ezamahlathi, okusanhlamvu neminye iminyango.

Ingase futhi isetshenziselwe izibonelo zezilwane nezitshalo, ukuhlonza nokuhlaziya ubufakazi yiminyango yezokuphepha yomphakathi, ucwaningo lokuhlola lwesayensi, njll.

Siyabonga ngokufunda kwakho.Uma udinga usizo olwengeziwe, sicela usithinte ngomusa.Ngiyabonga.
