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 ngokubona nokuqina. 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 prism asetha indinganiso entsha ye-optics kumasistimu wokucabanga we-fundus. Imele 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.
