Cov tsom iav kho qhov muag tam sim no siv dav hauv ntau qhov chaw, suav nrog cov koob yees duab, telescopes, microscopes, laser systems, fiber optic kev sib txuas lus, thiab lwm yam. Los ntawm kev tsim qauv zoo heev thiab kev tsim khoom siv thev naus laus zis,cov iav tsom iavtuaj yeem ua tau raws li qhov xav tau ntawm qhov muag pom hauv ntau daim ntawv thov sib txawv, muab kev ntes duab meej thiab raug thiab kev ua haujlwm kis tau zoo.

Ua ntej tawm hauv lub Hoobkas, lub lens yuav tsum tau ua ntau yam xws li kev tsim qauv, kev ua tiav, thiab kev sim. Kev tsim qauv yog thawj kauj ruam, thiab nws yog ib qho tseem ceeb heev uas yuav tsum nkag siab txog qhov xav tau ntawm lub lens.

Kev tsim cov iav tsom iav

Kev nkag siab txog qhov xav tau tuaj yeem pab kho qhov muag lens thiab cov neeg tsim qauv nkag siab txog cov kev xav tau ntawm cov neeg siv khoom thiab muab cov kev daws teeb meem uas haum rau cov kev xav tau tiag tiag.

Yog li, dab tsi yuav tsum nkag siab txog kev kho kom haum thiab tsim cov iav kho qhov muag?

Cov kev xav tau ntawm daim ntawv thov

Ua ntej tshaj plaws, koj yuav tsum qhia meej rau cov kws kho tshuab seb daim ntawv thov tshwj xeeb yog dab tsi rau kev siv lub lens kho qhov muag thiab cov kev cai ua haujlwm yog dab tsi. Cov xwm txheej thov sib txawv yuav muaj cov kev cai sib txawv rau cov kev cai, kev ua haujlwm kho qhov muag thiab cov ntaub ntawv ntawmcov iav tsom iav.

Piv txwv li, cov teb sib txawv xws li kev pom kev hauv computer, kev ntsuas kev lag luam, thiab kev thaij duab kho mob muaj cov kev cai sib txawv rau cov iav.

Cov kev cai ntawm kev ua haujlwm kho qhov muag

To taub cov kev cai rau cov kev teeb tsa kho qhov muag, suav nrog qhov ntev ntawm lub lens, qhov pom kev, kev cuam tshuam, kev daws teeb meem, qhov ntau thiab tsawg ntawm lub lens, thiab lwm yam. Cov kev teeb tsa no muaj feem cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub tshuab kho qhov muag. Raws li cov kev cai ntawm daim ntawv thov, txiav txim siab seb puas xav tau cov qauv tsim kho qhov muag tshwj xeeb, xws li cov iav aspherical, cov lim dej vignetting, thiab lwm yam.

Tsis tas li ntawd xwb, qhov ntau thiab tsawg ntawm daim ntawv thov lens kuj yuav tsum tau xav txog. Vim tias qhov tsim ntawm lub lens yuav tsum xav txog chromatic aberration, cov khoom siv thiab lwm yam ntxwv, nws yog qhov tsim nyog kom paub qhov ntau thiab tsawg ntawm lub lens thaum nws siv.

Yog tias koj siv lub teeb monochromatic, xws li lub teeb liab, lub teeb ntsuab, lub teeb xiav, thiab lwm yam, lossis siv lub teeb dawb puv spectrum, lossis siv ze infrared,luv-nthwv dej infrared, nruab nrab nthwv dej infrared, lub teeb infrared ntev, thiab lwm yam.

Ib lub lens optical

Cov kev cai ntawm cov txheej txheem kho tshuab

Ntxiv rau qhov yuav tsum tau ua kom pom kev zoo, kev tsim lub lens kuj tseem yuav tsum nkag siab txog cov kev cai kho tshuab, xws li qhov loj ntawm lub lens, qhov hnyav, kev ruaj khov ntawm lub tshuab, thiab lwm yam. Cov kev ntsuas no cuam tshuam rau kev teeb tsa thiab kev koom ua ke ntawm cov lens kho tshuab.

Scov kev cai tshwj xeeb ntawm ib puag ncig

Cov tsom iav kho qhov muag yuav ua haujlwm nyob rau hauv ib puag ncig tshwj xeeb, thiab qhov cuam tshuam ntawm cov yam ntxwv ib puag ncig xws li kub, av noo, thiab siab rau lub lens yuav tsum tau xav txog. Yog tias qhov chaw ua haujlwm hnyav lossis muaj cov kev cai tshwj xeeb, lub tsom iav kho qhov muag yuav tsum tau tiv thaiv lossis xaiv cov khoom siv tshwj xeeb.

Cov nqi tsim khoom thiab cov nqi yuav tsum tau ua

Cov neeg tsim qauv yuav txiav txim siab txog cov txheej txheem tsim khoom thiab tus nqi ntawm lub lens kho qhov muag raws li qhov xav tau ntawm daim ntawv thov thiab qhov yuav tsum tau ua kom ntau. Nws feem ntau suav nrog kev xaiv cov txheej txheem ua khoom, cov ntaub ntawv thiab cov txheej txheem txheej txheem, nrog rau kev ntsuam xyuas thiab tswj tus nqi.
