Iiprism zamehlo
Iiprism ziiglasi eziluqilima zamehlo eziphantsi kwaye zigudiswe zibe ziimilo zejometri kunye ne-optically ebonakalayo.I-engile, indawo, kunye nenani lemigangatho inceda ukuchaza uhlobo kunye nomsebenzi.Iiprism ziibhloko zeglasi ekhanyayo enemigangatho ekhazimlisiweyo ecaba kwii-engile ezilawulwa ngokuchanekileyo enye kwenye, uhlobo ngalunye lweprism lune-engile ethile egoba indlela yokukhanya.Iiprism zisetyenziselwa ukuphambukisa, ukujikeleza, ukuguqula, ukusasaza ukukhanya okanye ukuguqula i-polarization ye-beam yesiganeko.Ziluncedo ukusonga iinkqubo zamehlo okanye imifanekiso ejikelezayo.Iiprisms zingasetyenziselwa ukuguqula kunye nokubuyisela imifanekiso ngokuxhomekeke kwizicelo.Iikhamera ze-SLR kunye neebhayinotyhulasi zombini zisebenzisa iiprism ukuqinisekisa ukuba umfanekiso owubonayo ukwindawo yokuma ehambelana nento.Inye into ebalulekileyo ekufuneka uyigcine engqondweni xa ukhetha iprism kukuba umqadi ubonakalisa imiphezulu emininzi ngaphakathi kwe-optic, oku kuthetha ukuba ubude bendlela yokukhanya kwiprism bude kakhulu kunoko bunokuba ngaphakathi kwesipili.
Kukho iintlobo ezine eziphambili zeeprism ezisekwe kwimisebenzi eyahlukeneyo: iiprism zokusasazeka, ukutenxa, okanye iiprism zokubonisa, iiprism zokujikeleza, kunye neeprism zokufuduswa.Ukutenxa, ukufuduswa, kunye neeprism zokujikeleza zixhaphakile kwizicelo zemifanekiso;iiprism zokusasazwa zenziwe ngokungqongqo ukusasaza ukukhanya, ngoko ke azifanelekanga kuso nasiphi na isicelo esifuna imifanekiso esemgangathweni.Uhlobo ngalunye lweprism lune-engile ethile egoba indlela yokukhanya.Inye into ebalulekileyo ekufuneka uyigcine engqondweni xa ukhetha iprism kukuba umqadi ubonakalisa imiphezulu emininzi ngaphakathi kwe-optic, oku kuthetha ukuba ubude bendlela yokukhanya bude kunoko bekuya kuba njalo ngesipili.
Iiprisms zokusasazwa
I-Prism dispersion ixhomekeke kwijometri yeprism kunye ne-curve ye-dispersion curve, ngokusekelwe kwi-wavelength kunye nesalathiso sokuphindaphinda kwe-prism substrate.I-engile yokutenxa ubuncinane imisela eyona engile incinci phakathi kwereyi yesiganeko kunye nemitha esasazwayo.Ubude obuluhlaza bokukhanya buphambuka ngaphezu kobomvu, kunye noluhlaza okwesibhakabhaka ngaphezu kokubini obomvu kunye nohlaza;ebomvu idla ngokuchazwa njenge-656.3nm, eluhlaza njenge-587.6nm, kunye nebhlowu njenge-486.1nm.
Ukutenxa, ukuJikeleka, kunye neePrism zokufuduswa
Iiprism eziphambukisa umendo wemitha, zijikelezisa umfanekiso, okanye zisuse nje umfanekiso kwi-axis yawo yoqobo ziluncedo kwiinkqubo ezininzi zokucinga.Ukutenxa kwimitha yemitha kuqhele ukwenziwa kwii-engile ezingama-45°, 60°, 90°, kunye ne-180°.Oku kunceda ukucudisa ubungakanani benkqubo okanye uhlengahlengiso lwendlela yeray ngaphandle kokuchaphazela lonke ucwangciso lwesixokelelwano.Iiprism ezijikelezayo, ezifana neeprism zehobe, zisetyenziselwa ukujikelezisa umfanekiso emva kokuba ujikiwe.Iiprism zokufuduswa zigcina isalathiso sendlela ye-ray, kodwa zilungelelanise ubudlelwane bayo nesiqhelo.
