I-optical coating yinye okanye ngaphezulu kweeleya ezicekethekileyo zemathiriyeli ezifakwe kwi-optical component okanye i-substrate efana nelensi okanye isibuko, esitshintsha indlela i-optic ebonisa ngayo kwaye idlulise ukukhanya. I-AD_CLD781905-5-5-5-55-BB3B-136Bad58d_CTDE58BDE58BDE58BDE58BDE58B -136bad5cf58d_kunye neelensi zefoto. Olunye uhlobo luyi-high-reflector coating engasetyenziselwa ukuvelisa izibuko ezibonisa ngaphezu kwe-99.99% yokukhanya_cc781905-5cde-3194-bb3b-136bad5cf58 kubo. Nangona kunjalo, iileyiti zamehlo ezintsonkothileyo zibonisa ukubonakala okuphezulu kuluhlu lwamaza obude, kunye nokuchasana nokubonakalisa ngaphezulu kolunye uluhlu, olunokusetyenziswa ku ukuveliswa kwezihluzo ze-dichroic ezicwecwe zefilimu.

Eyona nto ilula yokugquma i-optical layers yintsimbi ecekethekileyo, efana ne-aluminiyamu, ethi ifakwe kwi-glass substrates ukwenza umphezulu wesipili. Isinyithi esisetyenzisiweyo sinquma iimpawu zokubonakalisa isibuko; I-aluminiyam yexabiso eliphantsi kwaye eyona nto ixhaphakileyo yokugquma, kwaye ivelisa umboniso ojikeleze i-88% -92% ngaphezulu kwespectrum ebonakalayo. Ixabiso elithe kratya yisilivere, enokubonakala kwe-95% -99% nakwi-infrared ekude, kodwa ihlupheka ngenxa yokuncipha kokubonakala (<90%) kwimimandla eluhlaza okwesibhakabhaka kunye ne-ultraviolet spectral. Elona xabiso liphezulu yigolide, enika okugqwesileyo (98% -99%) ukubonakaliswa kuyo yonke i-infrared, kodwa ukubonakaliswa okulinganiselweyo kumaza amaza amfutshane kuno-550 nm, okukhokelela kumbala wegolide oqhelekileyo.

​

Ngokulawula ubukhulu kunye nobuninzi beengubo zetsimbi, kunokwenzeka ukunciphisa ukubonakaliswa kunye nokwandisa ukuhanjiswa kwendawo ye-optical surface, okubangelwa isibuko se-half-silvered. Ezi ngamanye amaxesha zisetyenziswa "njengezipili zendlela enye". 

 

Olunye uhlobo oluphambili lwe-optical coating yi-dielectric coating (oko kukuthi ukusebenzisa izinto ezinesalathiso se-refractive esahlukileyo kwi-substrate). Ezi zakhiwe ngamaleko amancinci ezinto ezifana ne-magnesium fluoride, i-calcium fluoride, kunye nee-oxides zetsimbi ezahlukeneyo, ezifakwe kwi-optical substrate. Ngokukhetha ngononophelo ukwakheka okuchanekileyo, ukutyeba, kunye nenani lale maleko, kuyenzeka ukuba ulungelelanise ukubonakaliswa kunye nokuhanjiswa kwengubo ukuvelisa phantse naluphi na uphawu olufunwayo. I-coefficients yokubonakalisa iindawo ezingaphantsi kwe-0.2% inokufezekiswa, ivelise i-antireflection (AR) yokugqoka. Ngokwahlukileyo, ukubonakaliswa kunokunyuswa ukuya kukhulu kune-99.99%, ukuvelisa i-high-reflector (HR) yokugqoka. Umgangatho wokukhanya unokuthi ulungelelanise naliphi na ixabiso elithile, umzekelo ukuvelisa isibuko esibonisa i-80% kunye nokuhambisa i-90% yokukhanya okuwela kuyo, ngaphezu kolunye uluhlu lwamaza. Izipili ezinjalo zinokuthiwa beamsplitters, kwaye zisetyenziswe njengee-output couplers in lasers. Kungenjalo, umaleko ungaklanywa ngendlela ukuba isibuko sibonisa ukukhanya kuphela kwibhande elimxinwa le-oths producing.

 

Ukuguquguquka kwezinto zokwalekwa kwe-dielectric kukhokelela ekusetyenzisweni kwazo kwizixhobo ezininzi zenzululwazi kunye nezoshishino (ezinje ngelases, iimicroscopes zamehlo, iiteleskopu eziphinda-phindayo, kunye nee-interferometers) kunye nezixhobo zabathengi ezinjengeebhayinotyhulasi, izibuko, kunye neelensi zefoto.

​

Iileyile zeDielectric are esetyenziswa rhoqo phezu kweefilimu zetsimbi, nokuba zinike umaleko okhuselayo (njengakwisilicon dioxide phezu kwealuminium), okanye ukunyusa umboniso wefilimu yesinyithi. Iindibaniselwano zesinyithi kunye ne-dielectric zikwasetyenziselwa ukwenza iingubo eziphambili ezingenakwenziwa nayiphi na enye indlela. Omnye umzekelo yinto ebizwa ngokuba "yisipili esigqibeleleyo", esibonisa imbonakalo ephezulu (kodwa engagqibelelanga), enovakalelo oluphantsi ngokungaqhelekanga kubude bobude, i-engile, kunye nepolarization.

​

Ukuyilwa kwee-optical coatings kufuna ubuchule obukhethekileyo kunye namava. Kukho inani leenkqubo zesoftware ezisetyenziswa ngabayili bethu bezinto zokugquma. Kuzo naziphi na iiprojekthi ezibandakanya uyilo, ukuvavanya, ukulungisa iingxaki okanye uphando kunye nophuhliso lweengubo, qhagamshelana nathi kunye neWorld class Optical Coating designers baya kukunceda.
