Kev ceev faj rau kev siv lub tshuab microscope ua ke nrog lub koob yees duab digital
Cov koob yees duab digital tau dhau los ua qhov zoo heev rau kev yees duab microscopic niaj hnub no. Yooj yim thiab nrawm duab; Kev saib ua ntej, txuag, rho tawm, lossis luam tawm ntawm qhov chaw tau ua rau muaj kev txhim kho tshiab hauv micrography.
Tam sim no, feem ntau ntawm cov koob yees duab digital siv rau kev ntes cov duab microscopic yog cov koob yees duab digital (xws li NIKON4500, CANONG6, A620, thiab lwm yam), uas yog cov koob yees duab uas tsis tuaj yeem tshem tau nrog lub koob yees duab lo ntsiab muag. Qhov no yuav tsum tau ntxiv ib lub lens nruab nrab ntawm lub tshuab tsom iav thiab lub koob yees duab lens kom cov duab microscopic tshwm rau ntawm lub dav hlau focal ntawm lub koob yees duab - peb hu nws lub lens relay.
Qhov zoo ntawm lub lens no ncaj qha cuam tshuam rau qhov zoo ntawm cov duab microscopic. Muab hais tias tam sim no tsis muaj kev sib koom ua ke soj ntsuam tus qauv rau cov iav relay, thiab tsis muaj kev pom zoo ntawm cov neeg siv thiab cov neeg tsim khoom, nws nyuaj rau kev paub qhov zoo thiab qhov tsis zoo. Yog li ntawd, ntau manufacturers tau tshwm sim, thiab relay iav nyob rau hauv kev ua lag luam yog tov nrog zoo thiab phem. Raws li peb lub xyoo ntawm kev ua haujlwm hauv microscopes thiab peb txoj kev nkag siab ntawm kev yees duab digital, peb tau sib piv ntau cov duab coj los ntawm cov iav relay hauv tsev thiab txawv teb chaws, thiab tau sau ntau txoj hauv kev los txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm relay iav rau koj siv:
1, Duab loj
Nws yog feem ntau ntseeg tias nrog ib daim iav relay, tsuav yog cov duab tuaj yeem sau lub koob yees duab
Lub vijtsam LCD yog qhov ua tiav, nws yog daim iav tsim nyog. Lub peev xwm ntawm daim iav relay los sau lub vijtsam tsuas yog tus qauv yam tsawg kawg nkaus, thaum qee qhov xav tau lub koob yees duab optical zoom siv los ua kom lub vijtsam puv. Qhov no hom ntawm relay daim iav qhov kho qhov muag system yog flawed.
2, Txhim kho cov duab xim
Cov xim kho dua tshiab ntawm cov duab microscopic kuj yog tus qauv rau kev kuaj cov iav relay. Lub iav relay tsim nyog yuav tsum muaj xim ntawm cov duab coj los ua kom zoo ib yam li qhov pom los ntawm lub tshuab tsom.
3, Qhov tob ntawm daim teb ntawm ib daim duab
Cov neeg uas paub txog kev yees duab paub tias kev thaij duab yuav tsum muaj qhov tob ntawm qhov chaw (tshwj tsis yog kev yees duab kos duab). Peb txhua tus muaj qee qhov kev nkag siab ntawm hierarchy thaum saib cov duab microscopic. Lub lens tsim nyog relay yuav tsum muaj qhov tob ntawm qhov tsis tsawg tshaj li lub hom phiaj ntawm lub tshuab tsom.
4, Ntshiab ntawm cov duab
Qhov no yog qhov taw qhia tseem ceeb rau kev sim cov iav relay. Qhov hu ua "ntse" yog hais txog kev daws teeb meem, uas cuam tshuam ncaj qha rau qhov zoo ntawm cov duab microscopic.
Hauv luv luv, tus qauv zoo tshaj plaws rau kev txheeb xyuas daim iav relay yog los xyuas kom meej tias qhov zoo ntawm cov duab ntes tau los ntawm lub koob yees duab digital zoo ib yam nrog qhov pom hauv lub tshuab tsom mus rau qhov loj tshaj plaws.
