Qhov txawv ntawmiav opticalthiab lwm yam tsom iav yog tias raws li ib feem ntawm qhov kho qhov muag system, nws yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm optical imaging.
Nws cov txheej txheem txias txias siv cov tshuaj vapor cua sov kho thiab ib qho ntawm cov dej qab zib-lime silica iav los hloov nws cov qauv molecular yam tsis muaj kev cuam tshuam cov xim qub thiab lub teeb kis ntawm lub iav, ua rau nws ncav cuag tus qauv ultra-hardness, thiab ua tau raws li qhov hluav taws kub. kev tiv thaiv kev tiv thaiv nyob rau hauv high-temperature nplaim cuam tshuam Ultra-hard hluav taws-resistant iav thiab nws txoj kev tsim thiab cov khoom siv tshwj xeeb. Nws yog tsim los ntawm cov khoom hnyav hauv qab no: potassium ntsev vapor (72% ~ 83%), argon (7% ~ 10%), gaseous tooj liab chloride (8% ~ 12%), nitrogen (2% ~ 6%).
Qhov zoo ntawm optical iav muaj cov hauv qab no yuav tsum tau:
1. Qhov tshwj xeeb kho qhov muag tsis tu ncua thiab qhov sib xws ntawm cov khoom siv kho qhov muag ntawm tib lub khob iav
Txhua hom iav kho qhov muag muaj cov txheej txheem refractive index tus nqi rau qhov sib txawv wavelengths ntawm lub teeb, uas yog lub hauv paus rau optical designers tsim kho qhov muag tshuab. Cov khoom siv kho qhov muag ntawm txhua lub iav kho qhov muag uas tsim nyob rau hauv lub Hoobkas yuav tsum nyob rau hauv ib qho kev tso cai ntawm cov txiaj ntsig no, txwv tsis pub qhov kev pom zoo tiag tiag yuav tsis phim qhov kev xav tau thaum lub sij hawm tsim thiab qhov zoo ntawm cov cuab yeej kho qhov muag yuav raug cuam tshuam.
2. High Transparency
Cov duab ci ntsa iab ntawm qhov system kho qhov muag yog proportional rau lub pob tshab ntawm iav. Lub pob tshab ntawm cov iav kho qhov muag rau lub teeb ntawm qee qhov wavelength yog qhia los ntawm lub teeb nqus coefficient Kλ. Tom qab lub teeb hla dhau ntawm cov prisms thiab lo ntsiab muag, ib feem ntawm nws lub zog poob los ntawm kev cuam tshuam kev cuam tshuam ntawm qhov chaw kho qhov muag thiab lwm qhov yog absorbed los ntawm nruab nrab (iav) nws tus kheej. Tus qub tau nce nrog qhov nce ntawm qhov refractive index ntawm iav. Rau high-refractive-index iav, tus nqi no loj heev. Piv txwv li, lub teeb pom kev poob ntawm ib qhov chaw ntawm counterweight flint iav yog li 6%. Yog li ntawd, rau ib qho kev kho qhov muag uas muaj ntau lub lo ntsiab muag nyias, txoj hauv kev tseem ceeb los ua kom qhov kev xa tawm yog kom txo tau qhov kev xav tsis zoo ntawm lub lens nto, xws li txheej txheej nrog cov txheej tiv thaiv kev cuam tshuam. Rau qhov loj-loj kho qhov muag xws li lub hom phiaj lens ntawm astronomical telescope, transmittance ntawm optical system yog txiav txim siab los ntawm lub teeb haum coefficient ntawm iav nws tus kheej vim nws loj thickness. Los ntawm kev txhim kho lub purity ntawm iav raw cov ntaub ntawv thiab tiv thaiv tej xim impurities los ntawm kev sib tov nyob rau hauv tag nrho cov txheej txheem los ntawm batching mus rau smelting, lub teeb absorption coefficient ntawm lub iav feem ntau yuav tsawg tshaj li 0.01 (uas yog, lub teeb transmittance ntawm lub iav nrog ib tug purity ntawm purity ntawm cov iav raw cov ntaub ntawv thiab tiv thaiv cov xim impurities los ntawm kev sib tov nyob rau hauv tag nrho cov txheej txheem los ntawm batching mus rau smelting, lub teeb absorption coefficient ntawm iav feem ntau yuav tsawg tshaj li 0.01. thickness ntawm 1 cm yog ntau tshaj 99%).
Saida iavyog lub ntiaj teb no lees paub cov iav sib sib zog nqus ua cov khoom lag luam zoo, tus nqi sib tw thiab lub sijhawm xa khoom raws sijhawm. Nrog customizing iav nyob rau hauv ib tug ntau yam ntawm cov cheeb tsam thiab specializing nyob rau hauv kov vaj huam sib luag iav, hloov iav vaj huam sib luag, AG/AR/AF/ITO/FTO/Low-e iav rau sab hauv tsev & sab nraum zoov kov screen.
