Thaum nws los txog rau ntawm 3-18x50 SFIR rab phom tua phom, muaj qee yam ntxiv los xav txog:
Focal Plane: SFIR scopes feem ntau hu ua Thawj Focal Plane (FFP) scopes. Nyob rau hauv thawj lub dav hlau focal, cov kev hloov hauv magnification cuam tshuam qhov loj ntawm reticle nyob rau hauv lub Scope. Qhov no txhais tau hais tias txawm tias koj tab tom siv qhov ntsuas qis lossis siab, qhov reticle qhov loj yuav hloov raws li, tso cai rau koj siv lub reticle kom meej aiming ntawm ntau qib magnification.
Optical Coatings: High-quality scopes feem ntau ntiav ntau yam optical coatings los txhim kho lub teeb kis tau tus mob thiab cov duab zoo. Cov coatings no pab txo qhov kev xav thiab tawg, ua rau pom qhov ci dua thiab pom tseeb dua. Cov txheej txheem kho qhov muag muaj xws li cov txheej txheem tiv thaiv kev cuam tshuam, ntau txheej txheej, thiab cov txheej txheej tsis tshua muaj.
