Prism waa curiye indhaha ka soo celisa iftiinka xaglo gaar ah oo ku salaysan dhacdada iyo xaglaha bixitaanka.Prisms waxaa ugu horayn loo isticmaalaa hababka indhaha si loo beddelo jihada waddooyinka iftiinka, loo soo saaro rogaal-celinta ama leexinta, iyo awood u yeelashada hawlaha sawirka.
Prisms loo isticmaalo in lagu beddelo jihada iftiinka iftiinka ayaa guud ahaan loo qaybin karaa mid ka tarjumaysa prism
Milicsiga prisms waxaa lagu sameeyaa iyadoo lagu shiidi karo hal ama in ka badan oo sagxadaha milicsanaya gabal quraarad ah iyadoo la adeegsanayo mabda'a wadarta milicsiga gudaha iyo tignoolajiyada dahaarka.Wadarta milicsiga gudaha waxay dhacdaa marka fallaadhaha iftiinka ee ka soo baxa gudaha saqafka sare ay gaaraan xagal ka weyn xagasha muhiimka ah ee guud ahaan milicsiga gudaha, dhammaan fallaadhaha iftiinka ayaa dib uga soo muuqanaya gudaha.Haddii wadarta guud ee milicsiga gudaha ee iftiinka dhacdada uusan dhicin, dahaarka birta ah ee milicsada, sida qalinka, aluminium, ama dahab, ayaa loo baahan yahay in lagu dhejiyo dusha sare si loo yareeyo lumitaanka tamarta iftiinka ee dusha sare ee milicsiga.Intaa waxaa dheer, si loo kordhiyo gudbinta priism-ka oo loo yareeyo ama loo baabi'iyo iftiinka khaldan ee nidaamka, dahaarka ka-hortagga milicsiga ee kala duwanaansho gaar ah ayaa lagu dhejiyaa meelaha laga soo galo iyo kuwa ka soo baxa priism-ka.
Waxaa jira noocyo badan oo prisms ah oo ka tarjumaya qaabab kala duwan.Guud ahaan, waxa loo qaybin karaa prisms fudud (sida prism-xagalka saxda ah, prism pentagonal prism, Dove prism), saqafka saqafka, prism prism, prism prism, iwm.
Dib-u-celinta prisms waxay ku salaysan tahay mabda'a iftiinka iftiinka.Waxay ka kooban tahay laba dusha sare ee dib u soo celinta, iyo xariiqda ka sameysan isgoysyada labada dusha waxaa loo yaqaannaa geesta refractive.Xagasha u dhaxaysa labada dusha sare ee dib u celinaya waxa loo yaqaan xagasha refraction ee prism, oo uu matalo α.Xagasha u dhaxaysa fallaadhaha soo baxaya iyo fallaadhaha dhacdada waxaa loo yaqaan xagasha leexinta, oo uu matalo δ.Marka la eego priism-ka, xagasha refraction α iyo index refractive n waa qiyam go'an, iyo xagasha leexinta δ ee prismka refractive kaliya waxa ay isku beddeshaa xagasha dhacdada I ee shucaaca iftiinka.Marka dariiqa indho-indheynta ee iftiinka uu la siman yahay prism-ka soo celinaya, qiimaha ugu yar ee xagasha leexinta ayaa la helayaa, tibaaxuna waa:
Wedge-ka indhaha ama prism-ka wedge waxaa loo tixraacaa sida prism oo leh xagal aad u yar oo dib u celin ah.Xagasha leexashada dayacan awgeed, marka iftiinku u dhaco si toos ah ama ku dhawaad toosan, tibaaxaha xagasha leexinta ee jeexjeexa waxa loo fududayn karaa qiyaas ahaan sida: δ = (n-1) α.
Tilmaamaha dahaarka:
Caadi ahaan, aluminium iyo filimaan milicsi oo qalin ah ayaa lagu dhejiyaa dusha sare ee milicsiga si kor loogu qaado milicsiga iftiinka.Aflaanta ka-hortagga milicsiga ayaa sidoo kale lagu dahaadhay dhacdada oo meelaha bannaanka laga baxo si loo kordhiyo gudbinta iftiinka oo loo yareeyo iftiinka fog ee qaybaha kala duwan ee UV, VIS, NIR, iyo SWIR.
Goobaha codsiga: Prisms waxay ka helaan codsiyo ballaaran oo ku saabsan qalabka dhijitaalka ah, cilmi-baarista sayniska, qalabka caafimaadka, iyo qaybaha kale.- Qalabka dhijitaalka ah: kamaradaha, TV-yada wareegga-xiran (CCTV-yada), projectors, kamaradaha dhijitaalka ah, kamaradaha dhijitaalka ah, lenses CCD, iyo aaladaha indhaha ee kala duwan.- Cilmi-baadhis cilmiyaysan: telescopes, mikroskoobyada, heerarka/fiiriyaasha falanqaynta faraha ama aragtida qoryaha;beddelayaasha qorraxda;qalabka lagu cabbiro ee noocyada kala duwan.- Qalabka caafimaadka: cystoscopes / gastroscopes iyo sidoo kale qalabka daaweynta laser ee kala duwan.
Jiujon Optics waxay bixisaa noocyo kala duwan oo badeecooyin bir ah sida prisms-ka midig ee laga sameeyay galaaska H-K9L ama UV fused quartz.Waxaan bixinaa pentagon prisms, Dove prisms, saqafka saqafka, gees-cube prisms, UV fused silica gees-cube prisms, iyo prisms prisms ku habboon ultraviolet (UV), iftiinka muuqda (VIS), xirmooyin ku dhow-infrared (NIR) oo leh saxnaansho kala duwan heerarka.
Alaabooyinkaan waxaa lagu dahaadhay sida aluminium/silver/film milicsiga dahabka/filimka-milicsiga/ka ilaalinta nikel-chromium/ ilaalinta rinjiga madow.
Jiujon waxay bixisaa adeegyo prism la habeeyey oo ku habboon shuruudahaaga gaarka ah.Tan waxaa ka mid ah wax ka beddelka cabbirka/beegyada/ dookhyada dahaarka iwm. Xor baad u tahay inaad nala soo xiriirto faahfaahin dheeraad ah.
