Ikhavazi lezilaseri lezincwadi zisebenzisa umzimba we-Aluminum Oxide Al2O3 wokuthiwa yi-ceramic, okuyinto enkulu kakhulu kwezilaseri. Lolu hlobo lwe-ceramic lusebenza ngokuthi lusebenzelelwe ngokugcwele emhlabeni wokuthi lusebenzelele. Ukuboniswa kwezinto ezithile kuyadingeka. Izinto ezinhle kakhulu zezilwane zokubonisa zineqiniso elikhulu lokuboniswa kwezinkanyezi ngaphansi kwesibonelo esikhanyayo (380nm-780nm). Isidingo sezinhlamvu zokubonisa ngokwezincwadi kuyinto ukusebenza kwazo kakhulu.
