Optical coating chinhu chimwechete kana kupfuura chitete chechinhu chakaiswa pachikamu che optical kana substrate yakaita selenzi kana girazi, zvinoshandura nzira iyo optic inotaridza uye kutumira chiedza. A popular type ye optical coating is an antireflection (AR) coating, iyo inoderedza kuratidzwa kusingadikanwi kubva panzvimbo, uye inowanzoshandiswa pazviratidziro,_cc781905-5cde-3194-585-8bbd8b9bb8b9bb8b9bb8b9bb8b9bb8b9bb8b9bb3b9bb8b9bb3b9b9bb80ccd9bb3b9b9b9b9b9b9b9bb80bb8-dv8b9bb3b9b9b9b9b9b9b9b9b9bbd5-dv8b9bbd-31b9bb-8bbd-6bb-8bbd-60b9-dv -136bad5cf58d_uye mafoto lenzi. Imwe mhando ndeye high-reflector coating iyo inogona kushandiswa kugadzira magirazi anoratidza more than 99.99% yechiedza_cc781905-5cde-3194-bb3b-136bad5cf58d pavari. Zvakadaro, machira akaomesesa akaomesesa anoratidza kutarisisa kwepamusoro pamusoro peimwe wavelength renji, uye anti-reflection pamusoro peimwe siyana, iyo inogona kushandiswa mu kugadzirwa kwe dichroic nhete-firimu optical mafirita.

Iwo akapfava akapfava akapfava matete akaturikidzana esimbi, akadai sealuminium, ayo anoiswa pagirazi substrates kugadzira magirazi. Iyo simbi inoshandiswa inosarudza maitiro ekuratidzira kwegirazi; aruminiyamu yakachipa yakachipa uye yakajairika coating, uye inoburitsa ratidziro inosvika 88% -92% pamusoro peinooneka spectrum. Kunyanya kudhura isirivha, iyo ine reflectivity ye 95% -99% kunyange kusvika kure infrared, asi inotambura nekuderera kwekuratidzira (<90%) munzvimbo yebhuruu uye ultraviolet spectral. Yakanyanya kudhura igoridhe, iyo inopa yakanakisa (98% -99%) kuratidza mukati me infrared, asi kushoma kutaridzika pawavelengths ipfupi pane 550 nm, zvichikonzera iyo yakajairika ruvara rwegoridhe.

​

Nekudzora ukobvu uye kuwanda kwesimbi machira, zvinokwanisika kuderedza kutaridzika uye kuwedzera kutapurirana kwenzvimbo yemaziso, zvichikonzera girazi rehafu-sirivheri. Aya dzimwe nguva anoshandiswa se "one-way mirrors". 

 

Imwe mhando huru ye optical coating ndeye dielectric coating (kureva kushandisa zvinhu zvine refractive index yakasiyana kune substrate). Izvi zvinogadzirwa kubva kumatehwe matete emidziyo senge magnesium fluoride, calcium fluoride, uye akasiyana simbi oxides, ayo anoiswa pane optical substrate. Nekungwarira sarudzo yeiyo chaiyo kuumbwa, ukobvu, uye nhamba yeaya maturu, zvinokwanisika kugadzirisa kutaridzika uye transmissivity yejasi kuburitsa chero chinodiwa hunhu. Reflection coefficients yepasi pasi pe0.2% inogona kuwanikwa, ichigadzira antireflection (AR) coating. Sezvineiwo, iyo reflectivity inogona kuwedzerwa kusvika yakakura kupfuura 99.99%, ichigadzira yakakwira-reflector (HR) coating. Chiyero chekuratidzira chinogonawo kugadziridzwa kune chero kukosha, semuenzaniso kugadzira girazi rinoratidza 80% uye rinoendesa 90% yechiedza chinowira pairi, pamusoro peimwe siyana yewavelengths. Magirazi akadaro  anogona kunzi beamsplitters, uye anoshandiswa seanobuda couplers mune lasers. Neimwe nzira, iyo yekupfeka inogona kugadzirwa nenzira yakadai kuti girazi rinoratidzira mwenje chete muakatetepa bhendi yewaveleng band.

 

Iko kushandiswa kwakasiyana-siyana kwedielectric coatings inotungamira mukushandiswa kwavo mune akawanda esainzi uye maindasitiri optical zviridzwa (senge lasers, optical microscopes, refracting telescopes, uye interferometers) pamwe nemidziyo yevatengi senge mabinoculars, magirazi, uye mafoto lenzi.

​

Dielectric layers are inowanzo shandiswa pamusoro pemafirimu esimbi, kungave kupa danda rekudzivirira (sezviri musilicon dioxide pamusoro pealuminium), kana kuwedzera kutaridzika kwefirimu resimbi. Metal uye dielectric musanganiswa anoshandiswawo kugadzira machira epamusoro asingagone kuitwa chero imwe nzira. Mumwe muenzaniso nderinodaidzwa kuti "girazi rakakwana", iro rinoratidza kutarisisa kwepamusoro (asi kusina kukwana), nekunzwa kuderera kusingaite kune wavelength, kona, uye polarization.

​

Kugadzira maoptical coatings kunoda hunyanzvi hunyanzvi uye ruzivo. Kune akati wandei mapurogiramu esoftware ari kushandiswa nevagadziri vedu veoptical coating. Kune chero mapurojekiti anosanganisira dhizaini, kuyedza, kugadzirisa matambudziko kana kutsvagisa & kusimudzira machira, taura nesu uye yedu World class optical coating designers ichakubatsira.
