Muri rusange amatara y'imodoka agizwe n'ibice bitatu: itara ry'urumuri, akagarura-rumuri n'indorerwamo ijyanye nayo (indorerwamo ya astigmatism).
1. itara
Amatara akoreshwa mu matara y'imodoka ni amatara ashyushye, amatara ya halogen tungsten, amatara mashya y'ubushyuhe bwinshi n'ibindi.
(1) Itara rishyuha: umugozi waryo ukozwe mu nsinga ya tungsten (tungsten ifite aho ishongera cyane n'urumuri rukomeye). Mu gihe cyo gukora, kugira ngo itara rirusheho gukora, rizuzura umwuka udafite umwuka (azote n'uruvange rwayo rw'imyuka idafite umwuka). Ibi bishobora kugabanya imyuka y'insinga ya tungsten, byongera ubushyuhe bw'umugozi, kandi byongera imikorere myiza y'urumuri. Urumuri ruturuka ku itara rishyuha rufite ibara ry'umuhondo.
(2) Itara rya Tungsten halide: Itara rya Tungsten halide rishyirwa muri gazi idafite umwuka mu kintu runaka cya halide (nka iyode, chlorine, fluorine, bromine, nibindi), hakoreshejwe ihame rya tungsten halide recycling reaction, ni ukuvuga, tungsten iva mu gahu ihura na halogen kugira ngo ikore tungsten halide ihindagurika, ikwirakwira mu gace k'ubushyuhe bwinshi hafi y'agahu, kandi ibora n'ubushyuhe, bityo tungsten igasubizwa kuri filament. Halogen yarekuwe ikomeza gukwirakwira no kugira uruhare mu ihinduka ry'izenguruka rikurikira, bityo izenguruka rigakomeza, bityo bikarinda ihinduka rya tungsten no kwirabura kw'agahu. Ingano y'agahu ka Tungsten halogen ni nto, igishishwa cy'agahu kikozwe mu kirahuri cya quartz gifite ubushyuhe bwinshi n'imbaraga nyinshi za mekanike, munsi y'imbaraga zimwe, urumuri rw'itara rya Tungsten halogen rukubye inshuro 1.5 urw'itara rya incandescent, kandi ubuzima bwaryo burushaho kuba inshuro 2 kugeza kuri 3.
(3) Itara rishya ry’ubushyuhe bwinshi: Iri tara nta filime isanzwe rifite mu itara. Ahubwo, electrode ebyiri zishyirwa mu muyoboro wa quartz. Umuyoboro wuzuyemo xenon na trace metals (cyangwa halides z’icyuma), kandi iyo hari voltage ihagije ya arc kuri electrode (5000 ~ 12000V), gazi itangira gukora iyoni no gutanga amashanyarazi. Atome za gazi ziba ziri mu gihe cyo gushyuha kandi zigatangira gutanga urumuri bitewe n’impinduka mu rwego rw’ingufu za electron. Nyuma ya 0.1s, ingano nto y’umwuka wa mercure irahinduka hagati ya electrodes, maze amashanyarazi ahita yimurirwa mu itara rya mercure vapor arc, hanyuma yimurirwa mu itara rya halide arc nyuma y’uko ubushyuhe buzamutse. Nyuma y’uko urumuri rugeze ku bushyuhe busanzwe bw’itara, imbaraga zo kubungabunga isohoka rya arc ziba nke cyane (hafi 35w), bityo 40% by’ingufu z’amashanyarazi zishobora kuzigamwa.
