Black Painted Corner Cube Prism for Fundus Imaging System
Imininingwane
Incazelo Yomkhiqizo
Sethula ukwakheka kwethu kwakamuva ku-fundus imaging system optics - amaprism ekhoneni elipendiwe elimnyama. Le prism yakhelwe ukuthuthukisa ukusebenza nokusebenza kwezinhlelo ze-fundus imaging, ihlinzeka ochwepheshe bezokwelapha ngekhwalithi yesithombe ephezulu kanye nokunemba.
Ama-prism ekhoneni elipendiwe elimnyama le-cube prism ambozwe ngopende oyisiliva nomnyama oyisivikelo ezindaweni ezintathu ukuze kuqinisekiswe ukuqina nokuphila isikhathi eside ezindaweni ezidingakalayo zomtholampilo. Lokhu kwakhiwa okumazombezombe kwenza kube kuhle kumasistimu wokucabanga nge-fundus lapho ukunemba nokuthembeka kubaluleke kakhulu.
Ngaphezu kwalokho, indawo eyodwa ye-prism imbozwe nge-antireflection coating (AR), ethuthukisa ukusebenza kwayo kokubona. Lokhu kunamathela kunciphisa ukucwebezela okungafuneki kanye nokucwebezela, okuvumela ukucatshangelwa kwe-fundus okucacile, okuningiliziwe. Umphumela uwukucaca okuphakeme kwesithombe nokugqama, okuvumela ochwepheshe bezempilo ukuthi benze izinqumo ezinembile zokuxilonga nezokwelashwa ngokuzethemba.
Le ngxenye ye-optical yakhelwe ukuhlangabezana nezidingo eziqinile zezinhlelo ze-fundus imaging, ukuqinisekisa ukuhlanganiswa okungenazihibe nokusebenza okuphelele. Ubunjiniyela bayo obunembile kanye nezinto ezisetshenziswayo zekhwalithi ephezulu zikwenza kube isengezo esibalulekile kunoma yikuphi ukusethwa kwe-fundus imaging, okusiza ekwandiseni ukusebenza kahle kanye nokusebenza kahle kohlelo.
I-cube prism ekhoneni elipendiwe elimnyama iyisixazululo esiguquguqukayo nesithembekile se-fundus imaging esisebenza kahle kakhulu futhi sihlala isikhathi eside. Idizayini nokwakhiwa kwayo okuthuthukile kuyenza ilungele ukusetshenziswa ezindaweni ezihlukahlukene zemitholampilo, kusukela ezibhedlela nasemitholampilo kuya ezikhungweni zocwaningo nasezikhungweni zemfundo.
Ngokugxila kukhwalithi, ukusebenza nokuthembeka, ama-prism ekhoneni elimnyama eline-lacquered cube asetha indinganiso entsha ye-optics kumasistimu e-fundus imaging. Imelela intuthuko enkulu ekucabangeni kwezokwelapha, ukuhlinzeka ochwepheshe bezokunakekelwa kwempilo ngamathuluzi abawadingayo ukuze banikeze izinga eliphezulu lokunakekela ezigulini zabo.
Kafushane, i-cube prism ekhoneni elipendiwe emnyama iyingxenye yesimanjemanje ye-optical ethembisa ukuthuthukisa ukusebenza kwezinhlelo ze-fundus imaging. Ukuqina kwayo okukhethekile, ama-coatings athuthukisiwe nobunjiniyela obunembayo kuyenza ibe yimpahla ebaluleke kakhulu kochwepheshe bezokwelapha abafuna imiphumela yezithombe ezisezingeni eliphezulu kanye nokunemba kokuxilonga. Izwa umehluko emfanekisweni we-fundus onama-prism ekhoneni anopende omnyama futhi uthathe umkhuba wakho womtholampilo ufinyelele ezingeni eliphezulu eliphezulu.
