Dib-u-eegayaasha (Trihedral Prisms) - leexashada, barakaca
Sidoo kale loo yaqaan xabadaha geesaha, prisms-yadani waxay ka samaysan yihiin muraayad adag oo u oggolaanaya fallaadhaha soo galaya inay ka soo baxaan si isku mid ah, kaliya jihada ka soo horjeeda faafinta, iyada oo aan loo eegin jihada priismka. Corner Cube Retro Reflector wuxuu ku shaqeeyaa mabda'a Isku-darka Milicsiga Gudaha (TIR), milicsigu waa dareen dareen la'aan ah xagasha dhacdada, xitaa marka iftiinka dhacdada uu ka soo galo prism ka baxsan dhidibka caadiga ah, wali waxaa jiri doona milicsi adag 180 °. Tani waxay faa'iido leedahay marka toosinta saxda ah ay adag tahay oo muraayadda aan la isticmaali karin.
