I-Optical Prisms
Ama-Prism ama-optic engilazi aqinile agaywe futhi aphucuziwe abe yizimo zejometri kanye ne-optically ebalulekile.I-engeli, indawo, kanye nenani lezindawo kusiza ukuchaza uhlobo nomsebenzi.Ama-Prism amabhlogo engilazi yokubona enezindawo ezipholishiwe eziyisicaba kuma-engeli alawulwa kahle aya komunye nomunye, uhlobo lweprism ngalunye lune-engeli ethile egotshwa indlela yokukhanya.Ama-Prism asetshenziselwa ukuchezukisa, ukuzungezisa, ukuhlehlisa, ukusabalalisa ukukhanya noma ukushintsha ukuhlukaniswa komugqa wesigameko.Ziwusizo ekugoqeni amasistimu okubona noma izithombe ezizungezisayo.Ama-Prism angasetshenziswa ukuguqula nokubuyisela izithombe kuye ngezinhlelo zokusebenza.Amakhamera e-SLR nama-binoculars kokubili asebenzisa ama-prism ukuze kuqinisekiswe ukuthi isithombe osibonayo sisendaweni efanayo nento.Into eyodwa ebalulekile okufanele uyikhumbule lapho ukhetha i-prism ukuthi i-beam iveza izindawo eziningi ngaphakathi kwe-optic, lokhu kusho ukuthi ubude bendlela yokubona nge-prism bude kakhulu kunalokho obungaba ngaphakathi kwesibuko.
Kunezinhlobo ezine eziyinhloko zamaprism ezisuselwe emisebenzini ehlukene: amaprism okuhlakazeka, ukuchezuka, noma ama-reflection prism, ama-rotation prism, namaprism asuswayo.Ukuchezuka, ukugudluzwa, nokuzungezisa ama-prism kuvamile ezinhlelweni zokuthwebula izithombe;ama-prism okuhlakazeka enzelwe ngokuqinile ukukhanya okuhlakazayo, ngakho-ke awafanele noma yiluphi uhlelo lokusebenza oludinga izithombe zekhwalithi.Uhlobo ngalunye lwe-prism lune-engeli ethile egotshwa indlela yokukhanya.Into eyodwa ebalulekile okufanele uyikhumbule lapho ukhetha i-prism ukuthi i-beam iveza izindawo eziningi ngaphakathi kwe-optic, lokhu kusho ukuthi ubude bendlela yokubona bude kakhulu kunalokho obekungaba ngesibuko.
I-Dispersion Prisms
Ukuhlakazeka kwe-Prism kuncike kujometri yeprism kanye nejika layo lokuhlakazeka kwenkomba, ngokusekelwe kubude begagasi kanye nenkomba yokuphindaphinda kwe-prism substrate.I-engeli yokuchezuka okuncane icacisa i-engeli encane phakathi komreyi wesigameko kanye nemisebe edluliswayo.Ubude beza obuluhlaza bokukhanya buchezuka ngaphezu kokubomvu, futhi luhlaza okwesibhakabhaka ngaphezu kokubomvu nokuluhlaza;okubomvu kuvame ukuchazwa ngokuthi 656.3nm, okuluhlaza okotshani okungu-587.6nm, nokuluhlaza okwesibhakabhaka njengo-486.1nm.
Ukuchezuka, Ukuzungezisa, kanye namaPrism Okususwa
Ama-Prism achezukisa indlela ye-ray, azungezisa isithombe, noma avele asuse isithombe eksisi yaso yasekuqaleni awusizo ezinhlelweni eziningi zokuthwebula izithombe.Ukuchezuka kwemisebe kuvame ukwenziwa ngama-engeli angu-45°, 60°, 90°, no-180°.Lokhu kusiza ukufinyanisa usayizi wesistimu noma ukulungisa indlela ye-ray ngaphandle kokuthikameze konke ukusethwa kwesistimu.Ama-prism azungezisayo, njengama-prism amajuba, asetshenziselwa ukuzungezisa isithombe ngemva kokuthi sihlanekezelwe.Ama-prism asusayo agcina isiqondiso se-ray path, nokho alungise ukuhlobana kwawo kokujwayelekile.
