Milaffairs, isha iftiinka caadiga ah ee qalabka iftiinka ee qolka matoorka kaliya ma bixin doono iftiin, laakiin sidoo kale wuxuu iftiimiyaa iftiinka band infrared dhow. Inkasta oo xoogga iftiinka uusan sarreyn, waxay u horseedi doontaa faragelin gaar ah NVIS (nidaamka ku habboon aragga habeenkii). Waqtigan xaadirka ah, habka tooska ah ee waxtarka leh ee lagu baabi'inayo faragelinta noocan ah waa in la isticmaalo shaandhada infrared agteeda. Tani ma aha oo kaliya ka dhigaysa nidaamka ku habboon aragtida habeenkii inuu si caadi ah u shaqeeyo, laakiin sidoo kale waxay adkeynaysaa nidaamka aragga habeenkii ee cadowga inuu naga helo meel fog.

Waqtigan xaadirka ah, muraayadaha iftiinka-hooseeya ee iftiinka habeenkii ayaa u soo baxay jiilka afaraad, iyo saameynta saameynta waxay la mid tahay jiilka saddexaad (625 ~ 930 nm), laakiin dareenka ayaa la xoojiyay. Cilmi-baadhista noocan ah filtarrada infrared-ku dhow waxay inta badan ku salaysan tahay shaandhada caagga ah ee u dhow-infrared ee laga soo saaro Maraykanka iyo shaandhada muraayadda infrared ee u dhow ee laga soo saaro Jarmalka, halka heerka korriinka waddanku uu yahay mid dib-u-dhac ah, mana jirto shaandheyn ku dhow oo buuxin karta shuruudaha waafaqsanaanta aragtida habeenkii.

Furaha si loo soo saaro filtarrada infrared-ka dhow ee la kulma heerarka militariga waa in la isticmaalo midabaynta nuugista infrared-ka ee la baaray, sababtoo ah dhammaan midabada nuugista infrared-ka dhow ma buuxin karaan baahiyaha. Si loo buuxiyo shuruudaha waafaqsan aragtida habeenkii, nuugista infrared dhow waxaa loo isticmaali karaa kaligiis, isku dhafan ama lagu qaso dheehyada caagga ah ee caadiga ah, si ay u sameeyaan baaxaddeeda muuqaalka ah iyo dhalaalka NR ee u hoggaansamaya -1.0E + 00≤ NR ≤ 1.7E-10, iyo chromaticity chromaticity waxay buuxinaysaa shuruudaha midabka cagaarka habeenkii, aragtida cagaarka habeenka iyo iftiinka habeenkii Aragga habeenkii caddaan), gudbinta iftiinka muuqdaa kama yarayn 20%.

Nuugayaasha infrared-ka u dhow waxaa ka mid ah dheeha cyanine, phthalocyanines, quinones, midabada azo iyo dhismooyinka birta ah. Waxaa ugu wanaagsan in nuugista infrared uu leeyahay heerka nuugista hoose ee gobolka iftiinka muuqda, waxtarka nuugista sare ee gobolka infrared ee u dhow iyo nuugista ballaaran ee suurtogalka ah. Diyaarinta filtarrada indhaha waxay qabataa tignoolajiyada dheeha+polymer, kaas oo lagu dahaadhay karo dusha sare ama lagu dari karo inta lagu jiro polymerization.
