Xaashida Cufnaanta Dhexdhexaadka ah

Shaandheeyaha cufnaanta dhexdhexaadka ah waa nooc ka mid ah attenuator indhaha, kaas oo yarayn kara xoogga iftiinka.Ka dib marka iftiinka ka soo baxa gobolka iftiinka ee muuqda ilaa gobolka iftiinka infrared-ka ee u dhow uu soo maro shaandhada cufnaanta dhexdhexaadka ah, mawjadaha kala duwan ee dhererka ayaa la yareeyaa isla saami isku mid ah, si qaybta indhaha loo yareeyo isla saamiga.Gudbinta tamarta iftiinka waxaa lagu hayaa qiyaas ahaan siman inta lagu jiro bandowga ballaaran.Sido kale loo yaqaan filter cufnaanta dhexdhexaadka ah, filter dhexdhexaad ah, filter ND, filter attenuation filter, filter cufnaanta go'an, iwm.Milicsiga filtarrada ND waxay ka kooban yihiin daahan-filim khafiif ah, oo badanaa macdan ah, kuwaas oo lagu dabaqay substrate-ka dhalooyinka.Dahaarka waxaa loo hagaajin karaa kala duwanaanshaha hirarka dhererka gaarka ah.Dahaarka khafiifka ah ayaa ugu horreyntii ka tarjumaya iftiinka dib ugu noqoshada isha.Waxa loo baahan yahay in taxaddar la sameeyo si loo hubiyo in iftiinka iftiimaya aanu faragelin nidaamka habaynta.Shaandheeyayaasha ND nuugista waxay isticmaalaan substrate galaas si ay u nuugaan boqolleyda gaarka ah ee iftiinka.
