Njengoba sonke sazi,I-telecentric lensIngabe uhlobo olukhethekile lwelensi yezimboni lwenzelwe izinhlelo zokusebenza zombono womshini. Awukho umthetho ohleliwe wokukhethwa kwawo, futhi ikakhulukazi kuya ngokuthi kungahlangabezana nezidingo zokudubula.
Kanjani Ukukhetha ilensi ye-telecentric? Iziphi izinto okufanele zibhekwe?
Ngokuvamile, ngaphambi kokukhetha ilensi ye-telecentric, lezi zinto ezilandelayo zidinga ukubhekwa:
Ubude obugxile kanye nensimu yokubuka
Kuyadingeka ukuthi ukhethe ubude obufanelekile bokugxila kanye ne-lind angle ngokuya ngezidingo zoqobo zokusetshenziswa nosayizi nezimpawu zethagethi. Ubude obuphelele bokugxila bunganikeza ukulungiswa okuphezulu nemininingwane, ngenkathi izinkundla ezinkulu ze-engeli zingamboza indawo ebanzi.
Ubude obugxile belensi ye-telecentric buvame phakathi kuka-17mm no-135mm, kanye nokukhethwa kobude obugxile kakhulu kuncike ekutheni yini ohlose ukuyidubula. Izithombe ze-Landscape zingadinga ubude obugxile kakhulu, kanti abathwebuli bezindawo zokwakha bangadinga ngaphezu kwama-35mm.

Ikhwalithi ye-Optical
Khetha aI-telecentric lensNgomklamo wekhwalithi ephezulu kakhulu nenqubo yokukhiqiza ukuze uqinisekise ukucaca nokunemba kwesithombe sokubuka. Ikhwalithi ye-Optical ifaka izinto ze-lens, ubuchwepheshe be-coating, inkomba eye-reuapy yezakhi zelensi nokunye.
Usayizi we-Aperture
Usayizi we-aperture uthinta ukusebenza kwamalensi ezindaweni eziphansi zokukhanya kanye nokulawulwa kokujula kwangemuva. Ngokuvamile, i-aperture ye-F / 2.8 noma enkulu ilungele ukusetshenziswa ezindaweni ezimnyama, ngenkathi i-apertilu ye-F / 4 noma encane ilungele ukusetshenziswa ezindaweni ezikhanyayo.

Design and sakhiwo
Cabanga ukwakheka nezici zesakhiwo zeI-telecentric lens, njengohlelo lokulungiswa kwezingxenye ezigxile kakhulu, kugxile uhlelo lokulungiswa, i-lens coating neminye imisebenzi. Idizayini nokwakheka kwalezi zici kuzothinta ngqo kalula ukusetshenziswa kokusetshenziswa nokubhekwa kwelensi ye-telecentric.
Isabelomali kanye nezidingo zangempela
Lapho ukhetha ilensi ye-telecentric, kufanele futhi ulinganise izici ezahlukahlukene ngokuya ngesabelomali sakho kanye nezidingo zangempela zokubuka. Amanye ama-telecentric lens angabiza kakhulu, kepha anganikeza imiphumela ebuka kangcono; Kunemikhiqizo ethile yezomnotho ngokuya ngokusebenza nentengo nakho kungaba yisinqumo esihle. Ngokuvamile kunconywa ukukhetha imikhiqizo esebenzayo engabizi ngaphansi kwesisekelo sokufunwa komhlangano.
Brand and Service
Imikhiqizo ehlukene ingathinta ukusebenza nekhwalithi yelensi. Ngaphansi kwezimo ezijwayelekile, ukukhethwa kwemikhiqizo eyaziwayo nedumela elihle leI-telecentric lensImikhiqizo ingaqinisekisa ikhwalithi yomkhiqizo nensizakalo yokuthengisa ngemuva. Eminye imikhiqizo ingahlinzeka ngamawaranti omude noma inezikhungo zokulungiswa ezigunyaziwe.
Imicabango yokugcina:
Ngokusebenza nabasebenza ngochwepheshe eChuangan, bobabili abaklami nezokwakha baphathwe ngonjiniyela abanamakhono kakhulu. Njengengxenye yenqubo yokuthenga, ummeleli wenkampani angachaza imininingwane eminingi eqondile ngohlobo lwelensi ofisa ukuyithenga. Uchungechunge lukaChuangan lwelensi imikhiqizo lusetshenziselwa izinhlelo eziningi zezicelo, kusukela ekubhekeni, ukuskena, ama-drones, izimoto kuya ezinhlotsheni ezihlukile zamalensi aqediwe, angashintshwa futhi asetshenziswe ngokwezidingo zakho. Xhumana nathi ngokushesha okukhulu.
