I-optical coating ungqimba olulodwa noma ngaphezulu oluncane lwento efakwe engxenyeni ye-optical noma i-substrate efana nelensi noma isibuko, eshintsha indlela i-optic ebonisa ngayo futhi idlulise ukukhanya. Uhlobo oludumile uhlobo lwe-optical coating luyi-antireflection (AR), enciphisa ukubukeka okungafuneki okuvela endaweni, futhi luvame ukusetshenziswa kuma-spectacles,_cc781905-5cde-3194-5bblac-6bb80ccd9bb8-3194-5bb80-8bbd9b9bbd9bb8-3194-5bb80ccd9bbd9b9bb3b9bb8-3194-6ccd9bb8-3194-68bbd9b9b3b9b9bbd9b9b3b9b9b9bbd9b9b9b9b9b9db3b9b9b9b9b9b9b9bbd8-db3. -136bad5cf58d_namalensi ezithombe. Olunye uhlobo i-high-reflector coating engasetshenziswa ukukhiqiza izibuko reflecting more than 99.99% of the light_cc781905-5cde-3194-bb3b-136bad5cfd58 kubo. Kodwa-ke, ama-optical coating ayinkimbinkimbi kakhulu abonisa ukuboniswa okuphezulu ngaphezu kobubanzi obuthile be-wavelength, kanye nokuphikisa ukuboniswa kolunye uhla, olungasetshenziswa ku ukukhiqizwa kwezihlungi ze-dichroic thin-film optical.

Izingubo zokukhanya ezilula kakhulu izingqimba ezincanyana zezinsimbi, njenge-aluminium, ezifakwa kuma-substrates engilazi ukuze zenze indawo yesibuko. Insimbi esetshenzisiwe inquma izici zokubonisa zesibuko; I-aluminium ishibhile futhi ijwayeleke kakhulu ukunamathela, futhi ikhiqiza ukukhanya okungama-88% -92% ngaphezu kwe-spectrum ebonakalayo. Isiliva elibiza kakhulu, eline-reflection engu-95% -99% ngisho nakwi-infrared ekude, kodwa ihlushwa ukuncipha kokubonakala (<90%) ezindaweni ze-spectral eluhlaza okwesibhakabhaka kanye ne-ultraviolet. Okubiza kakhulu igolide, okunikeza ukukhanya okuhle kakhulu (98% -99%) kuyo yonke i-infrared, kodwa ukukhanya okulinganiselwe kumaza wamaza amafushane kuno-550 nm, okuholela kumbala wegolide ojwayelekile.

​

Ngokulawula ukushuba nokuqina kwezingubo zensimbi, kungenzeka ukunciphisa ukubukeka futhi ukwandise ukudluliswa kwe-optical surface, okuholela esibukweni se-half-silvered. Lezi ngezinye izikhathi zisetshenziswa "njengezibuko zendlela eyodwa". 

 

Olunye uhlobo oluyinhloko lwe-optical coating i-dielectric coating (okungukuthi ukusebenzisa izinto ezinenkomba ye-refractive ehlukile ku-substrate). Lezi zakhiwe ngezingqimba ezincane zezinto ezifana ne-magnesium fluoride, i-calcium fluoride, nama-oxide ensimbi ahlukahlukene, afakwa ku-optical substrate. Ngokukhetha ngokucophelela ukwakheka okuqondile, ukujiya, kanye nenombolo yalezi zingqimba, kungenzeka ukuvumelanisa ukubukeka nokudluliswa kwe-coating ukukhiqiza cishe noma yisiphi isici esifiselekayo. Ama-coefficients okubonisa ezindawo ezingaphansi kuka-0.2% angafinyelelwa, akhiqize i-antireflection (AR). Ngokuphambene, i-reflector ingakhushulwa ibe ngaphezu kuka-99.99%, ikhiqize i-high-reflector (HR) enamathela. Izinga lokubonisa ukukhanya lingacutshungulwa kunoma yiliphi inani elithile, isibonelo ukukhiqiza isibuko esibonisa u-80% futhi sidlulise u-90% wokukhanya okuwela kuso, phezu kolunye uhla lwamaza wamaza. Izibuko ezinjalo zingabizwa beamsplitters, futhi zisetshenziswe njengezixhumi eziphumayo kuma-lasers. Kungenjalo, ukunamathela kungaklanywa ngendlela ukuthi isibuko sibonisa ukukhanya kuphela ebhandeni elincane le-oths le-producing.

 

Ukushintshashintshashintsha kwezinto zokumboza nge-dielectric kuholela ekusetshenzisweni kwazo ezintweni eziningi zesayensi nezezimboni (njengama-lasers, ama-optical microscopes, ama-refracting telescopes, nama-interferometer) kanye namadivayisi abathengi afana nama-binoculars, izibuko, namalensi ezithombe.

​

Izendlalelo ze-Dielectric yilezi esetshenziswa njalo phezu kwamafilimu ensimbi, noma ukunikeza ungqimba oluvikelayo (njengaku-silicon dioxide phezu kwe-aluminium), noma ukuthuthukisa ukubukeka kwefilimu yensimbi. Izinhlanganisela zensimbi ne-dielectric nazo zisetshenziselwa ukwenza izimbotshana ezithuthukisiwe ezingeke zenziwe nganoma iyiphi enye indlela. Isibonelo esisodwa yilokho okubizwa ngokuthi "isibuko esiphelele", esibonisa ukukhanya okuphezulu (kodwa okungaphelele), nokuzwela okuphansi ngokungavamile kubude beza, i-engeli, kanye ne-polarization.

​

Ukuklama okunamathelayo okubonakalayo kudinga ubuchwepheshe obukhethekile nolwazi. Kunezinhlelo eziningi ze-software ezisetshenziswa abaklami bethu be-optical coating. Nganoma yimaphi amaphrojekthi ahilela ukuklama, ukuhlola, ukuxazulula izinkinga noma ucwaningo nokuthuthukiswa kwama-coatings, xhumana nathi kanye ne-World class Optical coating designers izokusiza.
