Zinc Selenide (ZnSe)
Lilense tsa Plano-Concave
Lilense tsa Plano-concave li sebetsa hantle ha ntho le setšoantšo li le ka har'a li-conjugate ratios, tse kholo ho feta 5:1 kapa ka tlase ho 1:5. Tabeng ena, hoa khoneha ho fokotsa ho ferekana ha spherical, coma, le ho khopama. Joalo ka lilense tsa plano-convex, ho fihlela katleho e kholo, bokaholimo bo kobehileng bo lokela ho shebana le sebaka se seholohali sa ntho kapa conjugate e sa feleng ho fokotsa phallo ea spherical (ntle le ha e sebelisoa ka li-laser tse nang le matla a phahameng moo sena se lokelang ho khutlisoa ho felisa monyetla oa ho ba teng. tsepamisa).
Lilense tsa ZnSe li loketse ka ho khetheha bakeng sa tšebeliso ea matla a phahameng a CO kapa CO2 lasers. Ho phaella moo, li ka 'na tsa fana ka phetisetso e lekaneng sebakeng se bonahalang ho lumella ho sebelisoa ha lebanta le bonahalang la ho tsamaisana, le hoja litšoantšo tsa morao li ka' na tsa bonahala haholoanyane. Paralight Optics e fana ka Lilense tsa Zinc Selenide (ZnSe) Plano-Concave (PCV) tse fumanehang ka lebone la Broadband AR le ntlafalitsoeng bakeng sa 2 µm - 13 μm kapa 4.5 - 7.5 μm kapa 8 - 12 μm spectral range e kentsoeng libakeng tseo ka bobeli. Ho roala hona ho fokotsa haholo ponahalo e phahameng ea bokaholimo, ho fana ka phetiso e tloaelehileng e fetang 92% kapa 97% ho pholletsa le mefuta eohle ea AR. Sheba li-graph bakeng sa litšupiso tsa hau.
