Ama-lens askenaIsetshenziswa kabanzi ku-AOI, ukuhlolwa kokuphrinta, ukuhlolwa kwendwangu okungabonisiwe, ukuhlolwa kwesikhumba, ukuhlolwa kwethrekhi yesitimela, ukuhlolwa kanye nokuhlunga kombala nezinye izimboni. Lo mbhalo uletha isingeniso kuLine Scan Lens.

Isingeniso kulayini we-Scan Lens

1) Umqondo weLine Scan Lens:

I-Line Array CCD Lens iyi-lens ephezulu yokusebenza kwe-FA ye-Line Sensor Sensor Camera ehambelana nosayizi wesithombe, usayizi we-pixel, futhi ingasetshenziswa ekuhlolweni okuhlukahlukene okunembayo.

2) Izici zeLine Scan Lens:

1. Yenzelwe ngokukhethekile izinhlelo zokusebenza zokuskena okuphezulu, kuze kufike ku-12k;

2. Umphezulu wethagethi ohambisanayo ohambelana nokucabanga okuhambisanayo ngu-90mm, usebenzisa ikhamera ye-Scan ende;

3. Ukulungiswa okuphezulu, ubukhulu be-pixel obuncane kuze kufike ku-5um;

4. Izinga eliphansi lokuhlanekezela;

5. Ukukhulisa u-0.2x-2.0x.

Ukucatshangelwa kokukhetha i-lens yomugqa

Kungani kufanele sicabangele ukukhethwa kwamalensi lapho ukhetha ikhamera? Amakhamera we-Common Line Scan njengamanje anezinqumo ze-1k, 2k, 4k, 6k, 6k, 8k, 8k, 8k, ama-pixel, kanye ne-14um, ukuze usayizi we-chip uvela ku-10.240mm (1kx10m) kuya ku-86.016mm (12kx7um) kuyahlukahluka.

Ngokusobala, interface c interface isekude nokuhlangabezana nezidingo, ngoba interface C interface ingaxhuma kuphela ama-chips ngosayizi omkhulu ongu-22mm, okungu-1.3 inches. Isibonisi samakhamera amaningi yi-F, M42X1, M72X0.75, njll. Izindawo zokuxhumana zelensi ezahlukahlukene ezihambelana nokugxila okuhlukile emuva (ibanga le-Flange), elinquma ibanga elisebenzayo lelensi.

1) Ukukhuliswa kwe-Optical (β, ukukhulisa)

Lapho ukulungiswa kwekhamera kanye nosayizi we-pixel kunqunywe, usayizi wezinzwa ungabalwa; Usayizi we-sensor uhlukaniswe yinsimu yokubuka (i-FOV) ilingana nokukhulisa okubonakalayo. β = CCD / FOV

2) isikhombimsebenzisi (Mount)

Kukhona ikakhulukazi c, m42x1, f, t2, leica, m72x0.75, njll. Ngemuva kokuqinisekisa, ungawazi ubude be-interface ehambisanayo.

3) Ibanga le-Flange

Ukugxila emuva kubhekisele ekude kusuka endizeni ebonakalayo yekhamera ku-chip. Ipharamitha ebaluleke kakhulu futhi inqunywa ngumkhiqizi wekhamera ngokuya nge-Optical Path Design. Amakhamera avela kubakhiqizi abahlukahlukene, ngisho nange-interface efanayo, angahle abe nokugxila okuhlukile emuva.

4) MTF

Ngokukhulisa okubonakalayo, isikhombimsebenzisi, kanye nokugxila emuva, ibanga lokusebenza kanye nobude bendandatho ehlanganyelwe. Ngemuva kokukhetha lezi, kunesinye isixhumanisi esibalulekile, ukubona ukuthi inani le-MTF lilungile ngokwanele? Onjiniyela abaningi ababukwayo abaqondi i-MTF, kodwa ngamalensi aphezulu, i-MTF kumele isetshenziselwe ukukala ikhwalithi ephezulu.

I-MTF ihlanganisa ingcebo yolwazi efana nokuqhathanisa, ukulungiswa, imvamisa yendawo, ukukhiqizwa kwe-chromatic, njll., Futhi kuveza ikhwalithi ye-Optical of the lens ngemininingwane enkulu. Hhayi ibanga lokusebenza kuphela nensimu yokubuka ihlangabezana nezidingo, kepha umehluko wemiphetho awumuhle ngokwanele, kodwa futhi nokuthi ukhetha ilensi ephakeme kakhulu kufanele icatshangelwe.
