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.
