Sechikamu chemaziso, mafirita anoshandiswawo zvakanyanya muindasitiri yeoptoelectronic. Mafirita anowanzo shandiswa kugadzirisa kusimba uye wavelength maitiro echiedza, ayo anogona kusefa, kupatsanura, kana kuwedzera chaiwo wavelength nzvimbo dzechiedza. Iwo anoshandiswa pamwe chete neoptical lenses mune akawanda maindasitiri. Tevere, ngatidzidzei nezve kuona uye kushandisa nzira dzemasefa pamwe chete.
Kuedza nzira dzemasefa
Pakuonekwa kwemasefa, dzimwe nzira dzehunyanzvi dzinowanzo shandiswa, uye dzinotevera ndedzimwe dzinowanzo shandiswa:
1.Chromaticity kuyerwa nzira
Chromaticity kuyerwa nzira inzira yekuyera uye kuenzanisa ruvara rwemafirita uchishandisa colorimeter kana spectrophotometer. Iyi nzira inogona kuongorora chromaticity mashandiro emafirita nekuverenga iyo colodhi yeruvara makosi uye mavara akasiyana siyana pawavelengths akasiyana.
2.Transmittance kuyerwa nzira
Iyo nzira yekuyeresa yekufambisa inogona kushandisa transmittance tester kuyera kutapurirana kwesefa. Iyi nzira inonyanya kushandisa mwenje sosi kuvhenekera sefa, uku uchiyera kusimba kwechiedza chinofambiswa, uye pakupedzisira kuwana data rekutumira.
3.Spectral analysis method
Spectral analysis method inzira yekushandisa spectrometer kana spectrophotometer kuita spectral analysis pasefa. Iyi nzira inogona kuwana iyo wavelength renji uye spectral hunhu hwekufambisa kwesefa kana kuratidza.
4.Polarization spectroscopy
Polarization spectroscopy inonyanya kushandisa polarization spectrometer kuona maitiro epolarization esefa. Nekutenderedza sampu uye kuongorora shanduko mukusimba kwechiedza chemuenzaniso, iyo polarization shanduko hunhu hwesefa inogona kuwanikwa.
5.Microscopic yekutarisa nzira
Microscopic observation method inoreva kushandiswa kwemaikorosikopu kuona chimiro chepamusoro uye chimiro chemukati chesefa, uye kutarisa kana sefa ine matambudziko akadai sekusvibiswa, kukanganisa, kana kukuvara.
Mhando dzakasiyana dzemafirita dzinoshandisa maitiro akasiyana uye zvinhu, uye kucherechedzwa kwemafirita kunogona zvakare kuve kwakavakirwa pane chaiwo mafirita emidziyo uye zvinodiwa zvekushandisa nekusarudza imwe kana dzimwe nzira dzekuona kuti iyo yakasarudzwa sefa inosangana nemhando uye kuita zvinodiwa.
Kushandiswa kwesefa
Mhando dzakasiyana dzemafirita dzinogona kuve dzakasiyana nhanho dzekushandisa uye dziviriro. Pazasi pane nzira dzakajairika dzekushandisa mafirita:
1. Sarudza rudzi rwakakodzera
Mhando dzakasiyana dzemafirita dzine mavara akasiyana uye mabasa, uye mhando yakakodzera inoda kusarudzwa zvichienderana nezvinodiwa chaizvo. Semuenzaniso, mafirita epolarization anonyanya kushandiswa kubvisa zviratidziro uye kuwedzera kusiyanisa kwemavara, nepo ultraviolet mafirita achinyanya kushandiswa kusefa ultraviolet mwaranzi.
2. Kuisa uye kugadzirisa
Mushure mekupedza kusarudzwa, isa sefa pamberi pekamera lens kana laser kuti uone kuti inogona kuve yakasimba uye yakachengeteka yakagadziriswa munzira yekuona.
3. Gadzirisa nzvimbo
Zvinoenderana nezvinodiwa chaizvo zvemamiriro ezvinhu, chinzvimbo chesefa chinogona kutenderedzwa kana kutamiswa kugadzirisa kona yekupinda, ruvara, kana kusimba kwechiedza. Izvo zvinofanirwa kucherechedzwa kuti usabata pamusoro pesefa kuti usasiya mafingerprints kana zvikweshwa zvinogona kukanganisa kunaka kwechiedza.
4. Mhando dzakawanda dzinoshandiswa pamwechete
Dzimwe nguva, kuti uwane mamwe akaomarara optical mhedzisiro, zvinodikanwa kushandisa imwe sefa pamwe chete nemamwe mafirita. Paunenge uchishandisa, zvakakosha kubhadhara kune mirairo yekudzivisa kushandiswa zvisina kunaka.
5. Kuchenesa nguva dzose
Kuti uchengetedze kushanda uye kujeka kwesefa, zvinodikanwa kugara uchichenesa sefa. Paunenge uchichenesa, zvinodikanwa kushandisa nyanzvi yekuchenesa lens bepa kana jira rekotoni kupukuta zvinyoronyoro pamusoro pesefa. Dzivisa kushandisa zvinhu zvakakasharara kana zvinonyungudutsa makemikari kudzivirira kukwenya kana kukuvadza sefa.
6. Kuchengetedza kunonzwisisika
Kuchengetwa kwemasefa kwakakoshawo. Kuwedzera hupenyu hwesevhisi yesefa, kana isiri kushandiswa, inofanirwa kuiswa munzvimbo yakaoma, inotonhorera, uye isina guruva kudzivirira kuratidzwa kwenguva refu kuchiedza chezuva kana kufurira kwenzvimbo dzekushisa kwepamusoro.
