Iskena amalensizisetshenziswa kakhulu ku-AOI, ukuhlolwa kokuphrinta, ukuhlolwa kwendwangu engalukiwe, ukuhlolwa kwesikhumba, ukuhlolwa kukamzila wesitimela, ukuhlola nokuhlunga imibala nezinye izimboni.Lesi sihloko siletha isingeniso kumalensi wokuskena komugqa.

Isingeniso Selensi Yokuskena Ngomugqa

1) Umqondo welensi yokuskena komugqa:

Ilensi ye-CCD yomugqa womugqa iyilensi ye-FA esebenza kakhulu yamakhamera ochungechunge lwezinzwa ezihambisana nosayizi wesithombe, usayizi wamaphikseli, futhi ingasetshenziswa ekuhlolweni okunembayo okuphezulu.

2) Izici ze-lens yokuskena komugqa:

1. Idizayinelwe ngokukhethekile izinhlelo zokusebenza zokuskena ezinokulungiswa okuphezulu, kufika ku-12K;

2. Ubukhulu obuhambisanayo bethagethi yendawo yokuthwebula ngu-90mm, kusetshenziswa ikhamera yokuskena yomugqa omude;

3. Ukulungiswa okuphezulu, ubuncane besayizi yephikseli kufika ku-5um;

4. Izinga lokuhlanekezela eliphansi;

5. Ukukhulisa 0.2x-2.0x.

Okucatshangwayo Ngokukhetha Ilensi Yokuskena Ulayini

Kungani kufanele sicabangele ukukhetha kwamalensi lapho sikhetha ikhamera?Amakhamera omugqa ojwayelekile wokuskena okwamanje anezinqumo ezingu-1K, 2K, 4K, 6K, 7K, 8K, no-12K, nosayizi wamaphikseli angu-5um, 7um, 10um, no-14um, ukuze usayizi we-chip usukela ku-10.240mm (1Kx10um) kuye ku-86.016mm (12Kx7um) kuyahlukahluka.

Ngokusobala, i-interface ye-C isekude ukuhlangabezana nezidingo, ngoba i-interface ye-C ingaxhuma kuphela ama-chips ngosayizi omkhulu we-22mm, okungama-intshi angu-1.3.I-interface yamakhamera amaningi i-F, M42X1, M72X0.75, njll. I-interface ye-lens ehlukene ihambisana nokugxila okuhlukile emuva (Ibanga le-Flange), elinquma ibanga lokusebenza le-lens.

1) Ukukhulisa okubonakalayo(β, Ukukhulisa)

Uma ukulungiswa kwekhamera nosayizi wephikseli sekunqunyiwe, usayizi wezinzwa ungabalwa;usayizi wenzwa ohlukaniswe umkhakha wokubuka(FOV) ulingana nokukhuliswa kwe-optical.β=CCD/FOV

2) Isixhumi esibonakalayo(Mount)

Kukhona ikakhulukazi C, M42x1, F, T2, Leica, M72x0.75, njll. Ngemva kokuqinisekisa, ungakwazi ukwazi ubude esibonakalayo esihambisanayo.

3) Ibanga le-Flange

Ukugxila emuva kubhekisela ebangeni elisuka endizeni yokubuka ikhamera ukuya ku-chip.Kuyipharamitha ebaluleke kakhulu futhi inqunywa umkhiqizi wekhamera ngokuya ngomklamo wayo wendlela yokubona.Amakhamera avela kubakhiqizi abahlukene, ngisho anokuxhumana okufanayo, angase abe nokugxila okuhlukile emuva.

4) I-MTF

Ngokukhuliswa kwe-optical, isixhumi esibonakalayo, nokugxila emuva, ibanga lokusebenza nobude beringi ehlangene kungabalwa.Ngemva kokukhetha lezi, kukhona esinye isixhumanisi esibalulekile, esiwukubona ukuthi inani le-MTF lilungile ngokwanele yini?Onjiniyela abaningi ababonakalayo abayiqondi i-MTF, kodwa kumalensi asezingeni eliphezulu, i-MTF kufanele isetshenziselwe ukukala ikhwalithi yokubona.

I-MTF ihlanganisa ingcebo yolwazi olufana nokuqhathanisa, ukulungiswa, imvamisa yendawo, ukushintshashintsha kwe-chromatic, njll., futhi iveza ikhwalithi yokubona yesikhungo kanye nonqenqema lwelensi ngokuningiliziwe.Akukhona nje kuphela ibanga lokusebenza kanye nenkundla yokubuka ehlangabezana nezidingo, kodwa umehluko wamaphethelo awulungile ngokwanele, kodwa nokuthi ukukhetha i-lens yokulungiswa okuphezulu kufanele kucatshangelwe kabusha.
