Taw qhia
Lub koob yees duab module yog ntau dua li cov duab sensor. Lub lens yog qhov tseem ceeb sib npaug- nws txiav txim siab seb lub koob yees duab pom dab tsi, cov duab ntse npaum li cas, thiab nws ua tau zoo npaum li cas hauv cov xwm txheej sib txawv. Txawm hais tias koj tab tom tsim kho kho endoscope, kev ruaj ntseg hauv tsheb, lossis cov neeg siv khoom siv webcam, xaiv lub lens zoo yog qhov tseem ceeb. Ntawm Kev Ntseeg, peb tau tsim lub koob yees duab modules rau ntau tshaj 30 xyoo, thiab kev xaiv lub lens yog ib feem tseem ceeb ntawm peb cov txheej txheem tsim. Kab lus no piav qhia txog hom lens sib txawv thiab yuav xaiv qhov zoo li cas.
Vim li cas Lens Matters
Hauv ib qho twglub koob yees duab sensor module, lub lens tsom teeb rau ntawm daim duab sensor. Lub siab - zoo sensor nrog lub lens tsis zoo ua rau cov duab tsis zoo. Lub lens zoo tuaj yeem pab kom lub ntsuas ntsuas me me ua tau zoo. Cov yam ntxwv tseem ceeb ntawm lub lens:
- Focal Length:Field of view thiab magnification
- Aperture (f-number):Lub teeb sib sau ua ke thiab qhov tob ntawm thaj chaw
