Amatara yimodoka muri rusange agizwe nibice bitatu: itara, itara hamwe nindorerwamo ihuye (indorerwamo ya astigmatism).
1. itara
Amatara akoreshwa mumatara yimodoka ni amatara yaka cyane, amatara ya halogen tungsten, amatara mashya-yaka cyane amatara arc nibindi.
.Mugihe cyo gukora, kugirango wongere ubuzima bwa serivisi yumuriro, itara ryuzuyemo gaze ya inert (azote hamwe nuruvange rwa gaze ya inert).Ibi birashobora kugabanya guhumeka kwinsinga ya tungsten, kongera ubushyuhe bwa filament, no kongera imikorere yumucyo.Itara riva kumatara yaka rifite ibara ry'umuhondo.
. gaze ya tungsten iva muri filament ikora hamwe na halogene kugirango itange halide ihindagurika ya tungsten, itandukana nubushyuhe bwo hejuru hafi ya filament, kandi ikabora nubushyuhe, kuburyo tungsten isubizwa muri filament.Halogen yarekuwe ikomeje gukwirakwira no kugira uruhare mu myitwarire ikurikiraho, bityo uruziga rukomeza, bityo bikarinda guhinduka kwa tungsten no kwirabura kw'itara.Tungsten halogen itara rinini ni rito, igikonoshwa gikozwe mubirahuri bya quartz hamwe nubushyuhe bwo hejuru hamwe nimbaraga za mashini nyinshi, munsi yimbaraga zimwe, umucyo wamatara ya tungsten halogen wikubye inshuro 1.5 iy'itara ryaka, kandi ubuzima ni 2 kugeza Inshuro 3.
.Ahubwo, electrode ebyiri zishyirwa imbere muri tari ya quartz.Umuyoboro wuzuyemo xenon hamwe nicyuma (cyangwa ibyuma bya halide), kandi iyo hari ingufu za arc zihagije kuri electrode (5000 ~ 12000V), gaze itangira ionize no gutwara amashanyarazi.Atome ya gaze imeze neza kandi itangira gusohora urumuri bitewe ningufu zingufu za electron.Nyuma ya 0.1s, umwuka muke wa mercure uhumeka hagati ya electrode, kandi amashanyarazi ahita yimurirwa mumashanyarazi ya mercure arc, hanyuma akoherezwa mumatara ya halide arc nyuma yubushyuhe buzamutse.Umucyo umaze kugera ku bushyuhe busanzwe bwumuriro, imbaraga zo gukomeza gusohora arc ziri hasi cyane (hafi 35w), bityo 40% yingufu zamashanyarazi zirashobora gukizwa.
