1 Performance parameters mushure mekuputira
Muchinyorwa chakapfuura, isu takaunza mabasa, misimboti, dhizaini software uye maitiro akajairwa ekuputira emafirimu akaonda akaonda. Muchikamu chino, tinosuma kuyedzwa kwemashure ekuputira parameters. Maitiro ekuita kwepamusoro pechikamu mushure mekuputira anosanganisira Transmittance (Transmittance), Reflectance (R), Absorptance (A), etc. Mukuwedzera, iyo absorptance (Transmittance) nezvimwe zvakadaro. Iyo yekuparadzira hunhu S (Scatter) yemufirimu wepamusoro inodawo kuongororwa uye kuongororwa.
Iyo transmittance T ireshiyo yesimba rekusimba kwechiedza rinopfuura nemufirimu kune chiitiko chiedza simba. Iyo reflectance R ndiyo chiyero chesimba resimba rinoratidzwa nepamusoro pekuvhara kune chiitiko simba. Absorption A ireshiyo yesimba rechiedza rinotorwa nefirimu layer kune chiitiko chesimba rechiedza. Kune aya matatu paramita, hukama hunotevera huripo:
T + R + A = 1
Ndiko kuti, chiyero chekutumira, kuratidzira uye kutorwa kwefirimu yefirimu ndiyo inogara iripo 1. Izvi zvinoreva kuti mushure mokunge chiedza chechiedza chichipfuura nemukati, chikamu chayo chinopfuudzwa, chikamu chacho chinoratidzwa kure, uye mamwe ose. inobatwa ne membrane.
On theoptical chikamukudhirowa, iyo transmittance kana reflectivity yefirimu pamusoro inodiwa, uye spectral renji uye chiitiko Angle pasi penzvimbo yekushandisa inoda kutsanangurwa zvakajeka. Kana polarization ichidikanwa zvakare, huwandu hwenzvimbo dzepolarization hunoda kutsanangurwa zvakajeka. Semuyenzaniso, izvo zvinodikanwa zvekupfeka mumufananidzo uri pazasi ndezvekuti pa770nm, iyo reflectivity haifaniri kunge iri pasi pe88% pa45 degree chiitiko, uye pa550nm, iyo transmittance inofanirwa kunge isiri pasi pe70% pa45 degree chiitiko.
Mukuwedzera kune pamusoro apa optical properties, iyo mechanical uye chemikemikari ye optical film layer inodawo kutariswa, kusanganisira kupfeka kuramba, kusimba, solubility yefirimu layer. Uye zvakare, iyo yemhando yepamusoro yemaziso mushure mekuputira inodawo kutariswa, kusanganisira izvo zvinodikanwa zvegomba, kukwenya, tsvina, tsvina, nezvimwe.
2 Nheyo ye spectrophotometer
Mubepa rino, isu tinotarisisa nezve optical maitiro eiyo firimu nzira dzekuyedza kuunza, mukuita, iyo huru Spectrophotometer (Spectrophotometer) uye Ellipsometer (Ellipsometer) yekuyedza iyo firimu paramita, spectrophotometer inogona kuyedza kutapurirana, kutaridzika uye kunyudza maitiro eiyo optical. zvigadzirwa. Iyo ellipsometer inogona kuyera ukobvu uye polarization maitiro eiyo firimu layer, uye musimboti wezvose wakafanana.
Chimiro chechishandiso chakadaro chinogona kukamurwa kuita zvikamu zviviri zvedanda rekugadzira chiteshi uye danda rekugamuchira chiteshi, apo kufambiswa kwechikamu kunoda kuongororwa, chikamu chinoiswa pakati pematanho maviri, kuitira kuti danda. inopfuura nemuenzaniso, apo kuratidzwa kwechikamu kunoda kuongororwa, chikamu chinoiswa kune rumwe rutivi rwematanho maviri, kuitira kuti danda rionekwe nemuenzaniso. Semuenzaniso, musimboti we spectrophotometer yekuyera kutapurirana kwemuenzaniso unoratidzwa mumufananidzo unotevera:
Mumufananidzo uri pamusoro, mugumo wekuruboshwe ndiyo chiteshi chekugadzira danda, uchishandisa yakafara spectrum mwenje sosi kuburitsa mwenje, uyezve kuburikidza nekupatsanurwa kwegiredhi uye kusarudzwa kwekutsemuka, inoburitsa chaiyo wavelength yechiedza, danda rinopfuura nepakati. iyo collimator 1, inova danda rakakomberedzwa, yobva yapfuura nepapolarizer inogona kutenderedza Angle, inova mwenje wepolarized, uye mwenje wepolarized unokamurwa kuita 2 matanda ne spectroscope mushure mekunge collimator 2 yaunganidzwa. Chiedza chechiedza chinoratidzwa mune referensi detector, uko mwenje wemwenje wakaunganidzwa unoshandiswa sechirevo chekugadzirisa kunyura kwesimba nekuda kwekushanduka kwechiedza, uye imwe mwenje mwenje inopfuura nemumuenzaniso, inoumbwazve necollimator 3 uye collimator. 4, uye inopinda detector kumucheto wekurudyi webvunzo. Muyedzo chaiyo, maitiro maviri esimba anowanikwa nekuisa uye nekutora yakaedzwa sampu, uye kuendesa sampuli kunogona kuwanikwa nekuenzanisa simba.
Nheyo yeellipsometer yakafanana nemusimboti weiyo spectrophotometer iri pamusoro, kunze kwekuti inotenderera 1/4 wave plate inowedzerwa sechinhu chemuripo mudanda rekutumira chiteshi uye chiteshi chekugamuchira, uye polarizer inowedzerwawo mugwara rekugamuchira. , kuitira kuti polarization maitiro emuenzaniso anogona kuongororwa zvakanyanya kushanduka. Mune zvimwe zviitiko, iyo ellipsometer ichashandisawo zvakananga yakafara spectrum mwenje sosi, uye inotora slit uye splitter spectrometer pamagumo ekugamuchira, yakasanganiswa nemutsara array detector, kuti uwane bvunzo yekuita yechikamu.
3. Muedzo wekutumira
Muyedzo yekutapurirana, kuitira kudzivirira kuratidzwa kweiyo detector inogamuchira mwenje wemwenje, iyo yekubatanidza sphere inowanzoshandiswa seanogamuchira, musimboti unoratidzwa sezvizvi:
Sezvinoonekwa kubva pamufananidzo uri pamusoro, iyo sphere yekubatanidza igomba rakaputirwa nechena diffuse reflection coating material pamadziro emukati, uye pane buri rehwindo pamadziro ebhora, iro rinoshandiswa segomba rechiedza chechiedza chechiitiko. uye gomba rekugamuchira remwenje detector. Nenzira iyi, chiedza chinopinda munharaunda yekubatanidza chinoratidzwa kakawanda kuburikidza nemucheka wemukati wemadziro, zvichiita chiedza cheyunifomu pamadziro emukati, uye chinogamuchirwa ne detector.
Semuenzaniso, chimiro chemudziyo unoshandiswa kuyedza kutapurirana kweplate yemaziso inoratidzwa pazasi
Mumufananidzo uri pamusoro, sampu yakaedzwa inoiswa patafura yekugadziridza iyo inogona kuchinjika mu x uye y nzira. Kutumira kwemuenzaniso kunogona kuongororwa pane chero nzvimbo nekombiyuta kutonga kwetafura yekugadzirisa. Iyo transmittance kugovera kwese flat girazi inogona zvakare kuwanikwa nekuongorora bvunzo, uye kugadzirisa kweyedzo kunoenderana nesaizi yedanda.
4. Reflectivity test
Pakuyerwa kweiyo optical film reflectivity, pane kazhinji nzira mbiri, imwe inoenderana kuyerwa uye imwe yacho ndeyeyero yakakwana. Iyo nzira yekuyera nayo inoda chiratidziro chine chiratidziro chinozivikanwa kuti chishandiswe sereferensi yekuenzanisa kuyedzwa. Mukuita, kuratidzwa kwegirazi rekutarisa kunoda kuverengerwa nguva nenguva nekuchembera kana kusvibiswa kweiyo firimu layer. Nokudaro, nzira iyi ine zvikanganiso zvekuyera zvinogona kuitika. Iyo nzira yekuyeresa yekuyeresa kuyerwa kunoda kurongeka kweratidziro yechishandiso chekuyedza pasina kuisa sampuli. Mumufananidzo uri pazasi, chimiro cheiyo classic VW mudziyo unopihwa kuti uwane yakakwana kuyerwa kwekuratidzwa kwemuenzaniso:
Mufananidzo wekuruboshwe uri pamufananidzo uri pamusoro unoratidza chimiro chakaita V chine magirazi matatu, M1, M2 uye M3. Kutanga, kukosha kwekusimba kwechiedza mune iyi modhi kunoedzwa uye kunyorwa seP1. Zvadaro, mumufananidzo wakarurama, muenzaniso uri pasi pekuedzwa unoiswa mukati, uye girazi reM2 rinotenderedzwa panzvimbo yepamusoro kuti rigadzire chimiro chakaita W. Iyo yakakwana reflectivity yemuenzaniso wakayerwa inogona kuwanikwa. Ichi chishandiso chinogona zvakare kuvandudzwa, semuenzaniso, sampu iri pasi pekuyedzwa yakashongedzerwa yakazvimiririra inotenderera tafura, kuitira kuti sampu iri pasi pekuyedzwa inogona kutenderedzwa kune chero Angle, nekutenderedza M2 girazi kune inoenderana chinzvimbo chekuratidzira, kuti uwane iyo danda rinobuda, kuitira kuti reflectivity yemuenzaniso inogona kuedzwa pamakona akawanda.
Semuenzaniso, chimiro chechishandiso chinoshandiswa kuyedza kutaridzika kweplate yemaziso inoratidzwa pazasi:
Mumufananidzo uri pamusoro, muenzaniso wakaedzwa unoiswa patafura yekushandura ye x / y, uye kuratidzira kwemuenzaniso kunogona kuongororwa pane chero nzvimbo kuburikidza nekombiyuta kutonga kwetafura yekugadzirisa. Kuburikidza neiyo scanning bvunzo, iyo inoratidzira yekugovera mepu yeiyo yakazara flat girazi inogona zvakare kuwanikwa.
