Vim tias lub tshuab tsom iav siv lub teeb pom kev thiab pom lub teeb muaj ntau qhov sib txawv ntawm wavelengths. Lub microscope tsis tuaj yeem tsim cov duab ntawm ib yam khoom uas me dua qhov ntev ntawm lub teeb nthwv dejIb yam khoom uas tsawg dua li ib nrab ntawm lub wavelength ntawm lub tshuab hluav taws xob lub teeb pom kev zoo tsis pom nyob rau hauv lub tshuab ntsuas..
Thaum koj siv lub tshuab tsom iav koj yuav tsum tsis txhob?
TSEEM CEEB: Tsis txhob siv qhov ua kom pom tseeb tsuas yog nrog lub hom phiaj lub hwj chim qis ! Nws yog qhov yooj yim heev los tsav lub hom phiaj los ntawm kev swb. Qhov no rhuav tshem cov swb thiab tuaj yeem khawb lub lens! Lub ratchet mechanism rau kev txav mus rau theem yog pov tawm ntawm kev sib raug zoo thaum tsuas yog ib lub pob qhov rooj tig thaum tsom.
Vim li cas microscope tsis ua haujlwm?
Kuaj saib seb koj lub tshuab tsom iav puas ntsaws rau hauv. Kos kom pom tias cov qij tau teeb tsa raug raug … uas qee zaum tshwm sim thaum xa khoom. Tshawb xyuas lub rheostat (lub teeb tswj lub teeb) ntawm sab ntawm lub tshuab tsom.
Dab tsi yog teeb meem tshwm sim hauv kev siv lub tshuab tsom iav?
Peb qhov yuam kev cuam tshuam nrog qhov no yog: ua ntej, kev nthuav dav siab; thib ob, hloov cov txheej txheem; Thib peb, tsis muaj kev xyaum Raws li cov kev ua yuam kev no, peb lub hauv paus ntsiab lus hauv kev siv lub tshuab ntsuas hluav taws xob ua haujlwm tau pom zoo raws li cov lus qhia rau cov kws phais uas hloov kho rau lub tshuab microscope.
Dab tsi yog qhov txwv ntawm kev siv lub teeb microscopy?
Qhov kev txwv tseem ceeb ntawm lub teeb tsom iav yog nws daws lub zogSiv lub hom phiaj ntawm NA 1.4, thiab lub teeb ntsuab ntawm wavelength 500 nm, qhov kev daws teeb meem yog ∼0.2m ua. Tus nqi no yuav yog kwv yees li ib nrab, nrog rau qee qhov tsis yooj yim, siv hluav taws xob ultraviolet ntawm luv luv wavelengths.
