Kev ua cov khoom siv raw hauv kev tsim cov iav tsom iav: Thaum lub sijhawm ua cov iav tsom iav yaj, cov hnab looj tes nitrile uas muaj cov leej faj tsawg tuaj yeem tiv thaiv cov khoom tsis huv xws li leej faj ntawm tes los ntawm kev sib xyaw rau hauv cov khoom siv iav, zam cov qhov tsis zoo xws li npuas thiab cov kab hauv iav, thiab cuam tshuam rau qhov sib xws ntawm lub lens. Thaum lub sijhawm txiav thiab sib tsoo ntawm cov khoom siv kho qhov muag xws li cov siv lead ua los ntawm quartz, cov hnab looj tes tuaj yeem tiv thaiv cov hws thiab roj ntawm tus neeg teb xov tooj txhais tes los ntawm kev ua qias tuaj rau ntawm qhov chaw ntawm cov khoom, thiab tib lub sijhawm tiv thaiv cov tshuaj sulfur los ntawm kev cuam tshuam nrog cov khoom siv kom ntseeg tau tias cov khoom siv huv thiab kev ua tau zoo.
Cov txheej txheem txheej: Thaum txheej lub lens, cov hnab looj tes nitrile uas muaj sulfur tsawg tuaj yeem tiv thaiv cov pa phem ntawm tus neeg teb xov tooj tes kom tsis txhob kov lub lens nto, cuam tshuam rau qhov lo thiab sib npaug ntawm cov txheej. Qhov muaj sulfur tuaj yeem cuam tshuam nrog cov khoom txheej, ua rau muaj qhov tsis zoo xws li qhov pinholes thiab tawg hauv cov txheej. Kev siv cov hnab looj tes nitrile uas muaj sulfur tsawg tuaj yeem tiv thaiv cov teeb meem no kom tsis txhob tshwm sim, xyuas kom meej tias lub lens tau txais cov txheej zoo, thiab txhim kho cov khoom siv kho qhov muag ntawm lub lens xws li lub teeb transmittance thiab reflectivity.
Kev ntxuav cov khoom hauv cov txheej txheem sib dhos lub lens: Thaum ntxuav ntau qhov ntawm lub lens, cov hnab looj tes nitrile uas muaj cov leej faj tsawg tuaj yeem tiv thaiv cov khoom tsis huv, plua plav, thiab lwm yam ntawm tus neeg teb xov tooj txhais tes kom tsis txhob ua rau cov khoom qias neeg, ua kom cov khoom huv. Tib lub sijhawm, cov khoom muaj cov leej faj tsawg tuaj yeem tiv thaiv cov hnab looj tes kom tsis txhob xeb cov khoom hlau, ua kom ntseeg tau tias qhov tseeb thiab kev ua tau zoo ntawm cov khoom.
