Chophimba chowala ndi chinthu chimodzi kapena zingapo zopyapyala zomwe zimayikidwa pagawo la kuwala kapena gawo lapansi monga lens kapena galasi, zomwe zimasintha momwe kuwala kumawonekera ndikutumiza kuwala. Chophimba chodziwika bwino mtundu wa zokutira ndi antireflection (AR), chomwe chimachepetsa kuwunikira kosafunika kuchokera pamwamba, ndipo chimagwiritsidwa ntchito kwambiri pazowonera,_cc781905-5cde-3194-5bblac5bb80ccd9bbd9b9bbd9b9bbd9b9bb8-3194-3195-5bb80-68bbd9b9bb8-db9-db3b3b94b9-db9b9b3b94b9-db9b9b3b94b9-db9b9b3b94b9-db9b9b3b94-3194-68-db9b9b94-3194-68-db9b9b94-3194-68-db9bbd9-db9. -136bad5cf58d_ndi magalasi ojambula. Mtundu wina ndi wokutira wonyezimira kwambiri womwe ungagwiritsidwe ntchito kupanga magalasi owonetsa more kuposa 99.99% ya kuwala_cc781905-5cde-3194-bb3b-136bad5cf58. Komabe, zokutira zovuta kwambiri zowoneka bwino zimawonetsa kuwunikira kwambiri pamitundu ina ya kutalika kwa mafunde, komanso kutsutsa-kuwunikira pamitundu ina, yomwe ingagwiritsidwe ntchito kupanga zosefera za dichroic thin-film Optical.

Zovala zosavuta kwambiri zowoneka bwino ndi zitsulo zopyapyala, monga aluminiyamu, zomwe zimayikidwa pagawo lagalasi kuti apange magalasi. Chitsulo chogwiritsidwa ntchito chimatsimikizira maonekedwe a galasi; aluminiyamu ndi yotsika mtengo kwambiri komanso yokutira wamba, ndipo imatulutsa chiwonetsero cha 88% -92% kuposa mawonekedwe owoneka. Zokwera mtengo kwambiri ndi siliva, yomwe imakhala ndi chiwonetsero cha 95% -99% ngakhale mu infrared yakutali, koma imavutika ndi kuchepa kwa chiwonetsero (<90%) m'madera a buluu ndi ma ultraviolet. Okwera mtengo kwambiri ndi golide, yemwe amapereka mawonekedwe abwino kwambiri (98% -99%) mu infuraredi yonse, koma kuwunikira kochepa pamafunde amfupi kuposa 550 nm, zomwe zimapangitsa kuti pakhale mtundu wagolide.

Poyang'anira makulidwe ndi kachulukidwe ka zokutira zachitsulo, ndizotheka kuchepetsa kuwunikira ndikuwonjezera kufalikira kwa mawonekedwe owoneka bwino, zomwe zimapangitsa galasi lasiliva la theka. Izi nthawi zina zimagwiritsidwa ntchito ngati "magalasi anjira imodzi". 

 

Mtundu wina waukulu wa zokutira zokutira ndi zokutira dielectric (mwachitsanzo kugwiritsa ntchito zida zokhala ndi index yosiyana ya refractive ku gawo lapansi). Izi zimapangidwa kuchokera kuzinthu zoonda kwambiri monga magnesium fluoride, calcium fluoride, ndi ma oxides osiyanasiyana achitsulo, omwe amayikidwa pagawo la kuwala. Posankha mosamalitsa mawonekedwe enieni, makulidwe, ndi kuchuluka kwa zigawo izi, ndizotheka kulinganiza kuwunikira ndi kutulutsa kwa zokutira kuti zipange pafupifupi mawonekedwe aliwonse omwe mukufuna. Ma coefficients owonetsera apansi ochepera 0.2% amatha kutheka, kupanga zokutira zotsutsa (AR). Mosiyana ndi izi, chiwonetserochi chikhoza kuwonjezeka kufika pa 99.99%, ndikupanga zokutira zapamwamba kwambiri (HR). Mulingo wa reflectivity ungathenso kusinthidwa ku mtengo wina uliwonse, mwachitsanzo kupanga galasi lomwe limawonetsa 80% ndikutumiza 90% ya kuwala komwe kumagwera pa izo, pamtundu wina wa wavelengths. Magalasi oterowo atha kutchedwa beamsplitters, ndipo amagwiritsidwa ntchito ngati opangira ma lasers. Kapenanso, zokutira zitha kupangidwa motere kuti galasi limawonetsa kuwala kokha mu gulu lopapatiza lozungulira, lozungulira lozungulira.

 

Kusinthasintha kwa zokutira za dielectric kumapangitsa kuti azigwiritsidwa ntchito pazida zambiri zasayansi ndi mafakitale (monga ma lasers, ma microscopes, ma telescope owonera, ndi ma interferometer) komanso zida za ogula monga ma binoculars, magalasi, ndi magalasi ojambula.

​

Zigawo za dielectric ndi zomwe zimagwiritsidwa ntchito kawirikawiri pamwamba pa mafilimu achitsulo, kuti apereke chitetezo (monga silicon dioxide pamwamba pa aluminiyamu), kapena kupititsa patsogolo kuwonetsetsa kwa filimu yachitsulo. Kuphatikiza kwachitsulo ndi dielectric kumagwiritsidwanso ntchito kupanga zokutira zapamwamba zomwe sizingapangidwe mwanjira ina. Chitsanzo chimodzi ndi chotchedwa "kalirole wangwiro", chomwe chimawonetsa kuwala kwakukulu (koma kosakwanira), kokhala ndi chidwi chochepa kwambiri cha kutalika kwa mafunde, ngodya, ndi polarization.

​

Kupanga zokutira zokutira kumafuna luso lapadera komanso chidziwitso. Pali mapulogalamu angapo apulogalamu omwe amagwiritsidwa ntchito ndi opanga athu opanga zokutira. Pama projekiti aliwonse okhudzana ndi mapangidwe, kuyesa, kuthetsa mavuto kapena kafukufuku & kakulidwe ka zokutira, lemberani ife ndi World class Optical coating designers adzakuthandizani.
