Muraayadaha indhaha

Muraayadaha indhaha waa qaybo indho-indhayn oo hufan oo leh meelo qalloocan oo dib u celin kara oo diiradda saari kara iftiinka.Waxaa si weyn loogu isticmaalaa hababka kala duwan ee indhaha si loo maamulo fallaadhaha iftiinka, hagaajinta aragga, weyneynta walxaha, iyo samaynta sawirro.Lenses-ku waa xubno muhiim u ah kamaradaha, telescopes, mikroskoobyada, muraayadaha indhaha, projectors, iyo aalado kale oo badan oo indhaha ah.

Waxaa jira laba nooc oo waaweyn oo lenses ah:

Lenses convex (ama isku dhafan).: muraayadahani waxa ay ka dhumuc weyn yihiin dhexda marka loo eego cidhifyada, waxaanay isu geeyaan fallaadhaha iftiinka is barbar socda ee dhex mara iyaga oo gaara meel ka soo horjeeda muraayada.Lenses convex ayaa caadi ahaan loo isticmaalaa muraayadaha waaweyneeya, kamaradaha, iyo muraayadaha indhaha si loo saxo aragtida fog.

Lenses concave (ama kala duwan).Lenses-yadani way ka khafiifsan yihiin cidhifyada dhexda, waxayna sababaan fallaadhaha iftiinka is barbar socda ee dhex mara si ay u kala duwanaadaan sidii iyagoo ka imanaya goob fican oo dhinaca muraayadda ah.Lenses concave ayaa inta badan loo adeegsadaa sixitaanka aragga dhow.

Muraayadaha waxaa loo qaabeeyey iyadoo lagu saleynayo dhererkooda fog, taas oo ah masaafada u jirta muraayadda ilaa barta diiradda.Dhererka fooxa ayaa go'aamiya heerka leexinta iftiinka iyo samaynta sawirka ka dhalanaysa.

Qaar ka mid ah ereyada muhiimka ah ee la xidhiidha muraayadaha indhaha waxaa ka mid ah:

Barta xudunta u ah: Meesha ay fallaaraha iftiinka ku kulmaan ama u muuqdaan inay kala duwan yihiin ka dib marka ay soo maraan muraayadda.Lens-ka qallafsan, waa barta ay fallaadhaha isbar-bar yaacayaan.Lenska concave, waa barta ay falaadhaha kala duwani u muuqdaan inay ka soo jeedaan.

Dhererka fooxa: Fogaanta u dhaxaysa muraayadda iyo barta diiradda.Waa halbeeg muhiim ah oo qeexaya awoodda muraayadda iyo cabbirka sawirka la sameeyay.

Aperture: Dhexroorka muraayada iftiinka u ogolaanaya inuu dhex maro.Daloolin weyn ayaa u oggolaanaya iftiin badan inuu dhaafo, taasoo keentay sawir dhalaalaya.

dhidibka indhaha: Xariiqda dhexe ee dhexmarta badhtamaha muraayada si siman oogihiisa.

Lens power: Waxaa lagu cabbiraa diopters (D), awoodda muraayadda waxay muujinaysaa awoodda dib-u-celinta ee muraayadda.Lenses convex waxay leeyihiin awoodo togan, halka muraayadaha concave ay leeyihiin awoodo taban.

Muraayadaha indhaha ayaa isbedelay dhinacyo kala duwan, laga soo bilaabo cilmiga xiddigiska ilaa cilmiga caafimaadka, iyaga oo noo oggolaanaya inaan u kuurgalno walxaha fog, dhibaatooyinka aragga saxo, oo aan samayno sawir iyo cabbiro sax ah.Waxay sii wadaan inay door muhiim ah ka ciyaaraan horumarinta tignoolajiyada iyo sahaminta sayniska.
