Hmo ntuj pom kev lo ntsiab muag yog hom optical lens uas txhim khu kev pom nyob rau hauv cov teeb pom kev zoo, tso cai rau tus neeg siv kom pom tseeb dua hauv qhov tsaus ntuj lossis qhov chaw tsis muaj teeb pom kev zoo.
Cov lo ntsiab muag no ua haujlwm los ntawm kev nthuav tawm cov teeb pom kev zoo, uas tuaj yeem yog ntuj lossis dag, los tsim cov duab ci dua. Ib txhiahmo ntuj pom kev lo ntsiab muagkuj tseem siv cov thev naus laus zis infrared los kuaj xyuas thiab nthuav dav cov cua sov kos npe, uas tuaj yeem muab cov duab pom tseeb dua txawm tias nyob hauv qhov tsaus ntuj.
Cov yam ntxwv ntawmhmo ntuj pom kev lo ntsiab muagtuaj yeem sib txawv nyob ntawm seb hom thiab qauv, tab sis ntawm no yog qee qhov nta uas koj tuaj yeem pom hauvhmo ntuj pom kev lenses:
Lub qhov muag pom kev hmo ntuj feem ntau yog siv los ntawm cov tub rog, tub ceev xwm, thiab cov neeg yos hav zoov los txhim kho lawv qhov pom thiab raug thaum ua haujlwm hmo ntuj. Lawv kuj tau siv nyob rau hauv qee hom kev soj ntsuam thiab kev ruaj ntseg daim ntawv thov, nrog rau hauv qee qhov kev ua si lom zem xws li saib noog thiab stargazing.
