1 Amapharamitha wokusebenza ngemuva kokumbozwa
Esihlokweni esandulele, sethule imisebenzi, izimiso, isoftware yokuklama kanye nezindlela ezivamile zokugqoka zamafilimu amancane optical.Kulesi sihloko, sethula ukuhlolwa kwemingcele ye-post-coating.Imingcele yokusebenza ebusweni bengxenye ngemva kokumboza ihlanganisa i-Transmittance (Transmittance), i-Reflectance (R), i-Absorptance (A), njll. Ngaphezu kwalokho, i-absorptance (Transmittance) njalonjalo.Isici esihlakazekayo S (I-Scatter) sendawo yefilimu sidinga ukuhlolwa futhi sihlaziywe.
I-transmittance T isilinganiso samandla okukhanya adlula kufilimu kuya kumandla okukhanya esigameko.I-refleance R isilinganiso samandla okuqina aboniswa ubuso be-coating kumandla esigameko.Ukumuncwa A isilinganiso samandla okukhanya amuncwa ungqimba lwefilimu kumandla okukhanya esigameko.Kulawa mapharamitha amathathu, ubudlelwano obulandelayo bukhona:
T + R + A = 1
Okusho ukuthi, isamba sokudlulisa, ukucabangela kanye nokumuncwa kwesendlalelo sefilimu yi-1 njalo. Lokhu kusho ukuthi ngemva kokuba i-beam yokukhanya idlula ulwelwesi, ingxenye yalo idluliswa, ingxenye yayo ibonakaliswe kude, kanti okunye. imuncwa ulwelwesi.
Useingxenye ye-opticalimidwebo, ukudluliswa noma ukubonakaliswa kwendawo yefilimu ngokuvamile kuyadingeka, futhi ububanzi be-spectral kanye ne-engeli yesigameko ngaphansi kwesimo sohlelo lokusebenza kudingeka kuchazwe ngokucacile.Uma i-polarization iyadingeka, ububanzi bezifunda ze-polarization budinga ukuchazwa ngokucacile.Njengesibonelo, izimfuneko zokumboza emfanekisweni ongezansi ukuthi ku-770nm, ukubukeka kwesithombe akufanele kube ngaphansi kuka-88% ku-45 degree izehlakalo, futhi ku-550nm, ukudlulisela kumele kungabi ngaphansi kuka-70% ku-45 degree incidence.
Ngaphandle kwezakhiwo ezingenhla ze-optical, izakhiwo zemishini namakhemikhali zesendlalelo sefilimu ye-optical nazo zidinga ukucatshangelwa, kufaka phakathi ukumelana nokugqoka, ukuqina, ukunyibilika kwesendlalelo sefilimu.Ngaphezu kwalokho, ikhwalithi ye-optical surface ngemva kokumboza nayo idinga ukucatshangelwa, kuhlanganise nezidingo zokugoba, imihuzuko, ukungcola, amabala, njll.
2 Umgomo we-spectrophotometer
Kuleli phepha, sigxila ezintweni ezibonakalayo zezindlela zokuhlola ifilimu ukwethula, ngokusebenza, iSpectrophotometer (Spectrophotometer) ne-Ellipsometer (Ellipsometer) ukuhlola amapharamitha wefilimu, i-spectrophotometer ingahlola ukudluliswa, ukubonakaliswa kanye nezici zokumuncwa kwe-optical. imikhiqizo.I-ellipsometer ingakala ukujiya nezici ze-polarization zesendlalelo sefilimu, futhi isimiso sakho kokubili siyefana.
Isakhiwo somshini onjalo singahlukaniswa sibe izingxenye ezimbili zesiteshi sokukhiqiza ugongolo kanye nesiteshi sokwamukela ugongolo, lapho ukudluliselwa kwengxenye kudinga ukuhlolwa, ingxenye ibekwe phakathi kweziteshi ezimbili, ukuze ugongolo. idlula isampula, lapho ukubonakaliswa kwengxenye kudinga ukuhlolwa, ingxenye ibekwe ohlangothini olufanayo lweziteshi ezimbili, ukuze i-beam ibonakale isampula.Njengesibonelo, umgomo we-spectrophotometer ukukala ukudluliswa kwesampula uboniswa esithombeni esilandelayo:
Emfanekisweni ongenhla, isiphetho esingakwesokunxele yisiteshi sokukhiqiza i-beam, kusetshenziswa umthombo wokukhanya obanzi we-spectrum ukuze kukhishwe ukukhanya, bese kuthi ngokuhlukanisa igridi nokukhetha okusikiwe, kukhiphe ubude begagasi obuthile bokukhanya, ugongolo luyadlula. i-collimator 1, iba yi-collimated beam, bese idlula ku-polarizer ekwazi ukuzungezisa i-Angle, ibe ukukhanya kwe-polarized, futhi ukukhanya kwe-polarized kuhlukaniswe ngemishayo emi-2 nge-spectroscope ngemva kokuqoqwa kwe-collimator 2.I-beam yokukhanya iboniswa kumtshina wereferensi, lapho i-beam yokukhanya eqoqiwe isetshenziswa njengereferensi yokulungisa ukukhukhuleka kwamandla ngenxa yokuguquguquka komthombo wokukhanya, futhi enye i-beam yokukhanya idlula kusampula, yenziwe kabusha yi-collimator 3 kanye ne-collimator. 4, bese ingena kumtshina ekugcineni kwesokudla sokuhlola.Esivivinyweni sangempela, amanani amabili wamandla atholakala ngokufaka nokukhipha isampula ehloliwe, futhi ukudluliswa kwesampula kungatholwa ngokuqhathanisa amandla.
Umgomo we-ellipsometer ufana nomgomo we-spectrophotometer engenhla, ngaphandle kokuthi ipuleti le-wave elijikelezayo elingu-1/4 lengezwa njengengxenye yesinxephezelo esiteshini esithumela ugongolo kanye nesiteshi sokwamukela, futhi i-polarizer nayo yengezwa esiteshini sokwamukela. , ukuze izici ze-polarization zesampula zingahlaziywa ngokuguquguqukayo.Kwezinye izimo, i-ellipsometer izophinda isebenzise ngokuqondile umthombo wokukhanya we-spectrum ebanzi, futhi yamukele i-slit ne-splitter spectrometer ekugcineni kokwamukela, kuhlanganiswe nomtshina wohlelo olulinganayo, ukuze kuzuzwe ukuhlolwa kokusebenza kwengxenye.
3. Ukuhlolwa kokudlulisela
Esivivinyweni sokudlulisela, ukuze ugweme ukubonakaliswa komtshina othola i-beam yokukhanya, i-sphere ehlanganisayo ivame ukusetshenziswa njengomamukeli, isimiso siboniswa kanje:
Njengoba kungase kubonakale emfanekisweni ongenhla, i-sphere ehlanganisayo iyi-cavity sphere embozwe ngezinto ezimhlophe ezihlukanisayo ezibonisa ukukhanya odongeni lwangaphakathi, futhi kunembobo yefasitela odongeni lwebhola, esetshenziswa njengembobo yokukhanya yokukhanya kwesigameko. kanye nembobo eyamukelayo yomtshina wokukhanya.Ngale ndlela, ukukhanya okungena ku-sphere ehlanganisayo kubonakala izikhathi eziningana nge-internal wall coating, okwenza ukukhanya okufanayo odongeni lwangaphakathi, futhi kwamukelwa umtshina.
Njengesibonelo, ukwakheka kwedivayisi esetshenziselwa ukuhlola ukudluliswa kwe-optical plate kuboniswe ngezansi
Emfanekisweni ongenhla, isampula elihloliwe libekwe etafuleni lokulungisa elingagudluzwa kuzikhombisi-ndlela zika-x kanye no-y.Ukudluliswa kwesampula kungahlolwa kunoma yisiphi isikhundla ngokulawula ikhompuyutha yetafula lokulungisa.Ukusatshalaliswa kokudluliswa kwayo yonke ingilazi eyisicaba nakho kungatholwa ngokuhlolwa kokuskena, futhi ukuxazululwa kokuhlolwa kuncike kusayizi wendawo we-beam.
4. Ukuhlolwa kwe-Reflectivity
Ukuze kulinganiswa i-optical film reflectivity, ngokuvamile kunezindlela ezimbili, eyodwa iyisilinganiso esilinganiselwe kanti enye iyisilinganiso esiphelele.Indlela yokulinganisa ehlobene idinga isibonisi esinokubonisa okwaziwayo ukuthi sisetshenziswe njengereferensi yokuhlola ukuqhathanisa.Empeleni, ukubonakaliswa kwesibuko sesithenjwa kudinga ukulinganiswa njalo ngokuguga noma ukungcoliswa kongqimba lwefilimu.Ngakho-ke, le ndlela inamaphutha okulinganisa angaba khona.Indlela yokulinganisa okuphelele kokubukeka idinga ukulinganiswa kokubonakala kwedivayisi yokuhlola ngaphandle kokubeka isampula.Emfanekisweni ongezansi, ukwakheka kwedivayisi ye-VW yakudala kunikezwa ukuze kufinyelelwe isilinganiso esiphelele sokubonakala kwesampula:
Umfanekiso ongakwesokunxele kulo mfanekiso ongenhla ubonisa isakhiwo esimise okwe-V esinezibuko ezintathu, i-M1, M2 kanye ne-M3.Okokuqala, inani lamandla okukhanya kule modi liyahlolwa futhi lirekhodwe njenge-P1.Khona-ke, emfanekisweni olungile, isampula esivivinywayo ifakwa, futhi isibuko se-M2 sizungeziswa endaweni ephezulu ukuze sakhe isakhiwo esimise okwe-W.Ukubonakaliswa okuphelele kwesampula esilinganisiwe kungatholakala.Le divayisi ingabuye ithuthukiswe, isibonelo, isampula ngaphansi kokuhlolwa futhi ifakwe ithebula elizungezayo elizimele, ukuze isampula ngaphansi kokuhlolwa sikwazi ukuzungeziswa kunoma iyiphi i-Engeli, ngokuzungezisa isibuko se-M2 siye endaweni ehambisanayo yokubonisa, ukuze kuzuzwe okukhipha ugongolo, ukuze reflectivity of isampula ingahlolwa at engele amaningi.
Njengesibonelo, ukwakheka kwedivayisi esetshenziselwa ukuhlola ukubukeka kwepuleti le-optical kuboniswe ngezansi:
Emfanekisweni ongenhla, isampula esihloliwe sibekwe etafuleni lokulungiswa kokuhumusha kwe-x/y, futhi ukubukeka kwesampula kungahlolwa kunoma yisiphi isikhundla ngokulawulwa kwekhompyutha kwetafula lokulungiswa.Ngokuhlolwa kokuskena, imephu yokusabalalisa ekhombisayo yayo yonke ingilazi eyisicaba nayo ingatholakala.
