I-Prism iyisici esibonakalayo esiphindisela ukukhanya kuma-engeli athile ngokususelwe kusigameko sayo nama-engeli aphumayo.Ama-Prism asetshenziswa ngokuyinhloko ezinhlelweni zokubona ukuze kuguqulwe isiqondiso sezindlela ezikhanyayo, ukukhiqiza ukuguquguquka kwesithombe noma ukuphambuka, futhi unike amandla imisebenzi yokuskena.
Ama-Prism asetshenziselwa ukushintsha isiqondiso semishayo yokukhanya ngokuvamile angahlukaniswa abe yi-prism ekhombisayo kanye ne-refracting prism.
Ama-prism abonisayo enziwa ngokugaya indawo eyodwa noma ngaphezulu ecwebezelayo ocezwini lwengilazi kusetshenziswa isimiso sokubonisa okuphelele kwangaphakathi nobuchwepheshe bokumboza.Ukuboniswa okuphelele kwangaphakathi kwenzeka lapho imisebe yokukhanya evela ngaphakathi kweprism ifinyelela phezulu nge-engeli enkulu kune-engeli ebalulekile yokubonakala okuphelele kwangaphakathi, futhi yonke imisebe yokukhanya iboniswa emuva ngaphakathi.Uma ukuboniswa okuphelele kwangaphakathi kokukhanya kwesigameko kungeke kwenzeke, i-metallic reflective coating, njengesiliva, i-aluminium, noma igolide, idinga ukufakwa endaweni engaphezulu ukuze kuncishiswe ukulahlekelwa kwamandla okukhanya endaweni ekhanyayo.Ngaphezu kwalokho, ukuze kwandiswe ukudluliswa kwe-prism futhi kuncishiswe noma kuqedwe ukukhanya okulahlekile ohlelweni, ama-anti-reflection coatings ebangeni elithile le-spectral afakwa endaweni yokungena nokuphuma kwe-prism.
Kunezinhlobo eziningi zama-prism akhanyayo ahlukahlukene.Ngokuvamile, ingahlukaniswa ngama-prism alula (afana ne-right-angle prism, i-pentagonal prism, i-Dove prism), i-roof prism, i-pyramid prism, i-compound prism, njll.
Ama-prism aphindwayo asekelwe kumgomo wokuphindaphinda ukukhanya.Iqukethe izindawo ezimbili ze-refractive, futhi umugqa owenziwe ukuphambana kwezindawo ezimbili ubizwa ngokuthi i-refractive edge.I-engeli ephakathi kwezindawo ezimbili eziphikisayo ibizwa ngokuthi i-engeli yokuphikisa yeprism, emelwe ngu-α.I-engeli ephakathi komsebe ophumayo kanye nomsebe wesigameko ibizwa ngokuthi i-engeli yokuchezuka, emelelwa ngu-δ.Ku-prism ethile, i-engeli ye-refraction α kanye ne-refractive index n amanani angashintshi, futhi i-engeli yokuchezuka engu-δ ye-refractive prism ishintsha kuphela nge-engeli yesigameko I yomsebe wokukhanya.Uma indlela yokubona yokukhanya ilingana neprism ephindayo, inani elincane le-engeli yokuchezuka liyatholwa, futhi isisho sithi:
I-optical wedge noma i-wedge prism ibizwa ngokuthi i-prism ene-engeli encane kakhulu yokuhlehlisa.Ngenxa ye-engeli yokuhlehla enganakeki, lapho ukukhanya kwenzeka ngokuqondile noma cishe mpo, isisho se-engeli yokuchezuka yeweji singacishe senziwe lula njengokuthi: δ = (n-1) α.
Izici zokumboza:
Ngokuvamile, amafilimu abonisa i-aluminium nesiliva asetshenziswa endaweni ekhanyayo ye-prism ukuze kuthuthukiswe ukukhanya.Amafilimu e-anti-reflection nawo ambozekile esigamekweni nasezindaweni zokuphuma ukuze akhulise ukudluliswa kokukhanya futhi anciphise ukukhanya okunhlanhlathayo kumabhendi ahlukahlukene e-UV, VIS, NIR, kanye ne-SWIR.
Izinkambu zokufaka isicelo: Ama-Prism athola izinhlelo zokusebenza eziningi kumishini yedijithali, ucwaningo lwesayensi, amathuluzi ezokwelapha, nezinye izizinda.- Imishini yedijithali: amakhamera, ama-TV avaliwe (ama-CCTV), ama-projektha, amakhamera edijithali, amakhamera edijithali, amalensi e-CCD, kanye namadivayisi ahlukahlukene okubona.- Ucwaningo lwesayensi: izibonakude, ama-microscopes, amazinga/okugxilwe kukho kokuhlaziywa kwezigxivizo zeminwe noma okubonwa ngezibhamu;ama-solar converters;amathuluzi okulinganisa ezinhlobo ezahlukene.- Amathuluzi ezokwelapha: ama-cystoscopes/gastroscopes kanye nemishini yokwelapha nge-laser ehlukene.
I-Jiujon Optics inikeza uchungechunge lwemikhiqizo ye-prism efana namaprism e-engeli kwesokudla enziwe ngengilazi ye-H-K9L noma i-UV fused quartz.Sihlinzeka ngama-pentagon prism, ama-Dove prism, ama-Roof prism, ama-prism ekhoneni-cube, ama-prism ekhoneni le-silica ehlanganisiwe ye-UV, nama-wedge prism afanele i-ultraviolet (UV), ukukhanya okubonakalayo (VIS), amabhendi e-infrared (NIR) anokunemba okuhlukahlukene. amazinga.
Le mikhiqizo inamekwe njengefilimu ebonisa i-aluminium/isiliva/igolide/ifilimu ephikisana ne-reflection/ukuvikelwa kwe-nickel-chromium/ukuvikela ngopende omnyama.
I-Jiujon inikezela ngezinsizakalo ezenziwe ngezifiso ze-prism ezihambisana nezidingo zakho ezithile.Lokhu kufaka phakathi ukulungiswa kosayizi/amapharamitha/okuncanyelwayo kokunameka njll. Zizwe ukhululekile ukusithinta ukuze uthole imininingwane eyengeziwe.
