Girazi rakavharidzirwa rinoratidza kupisa, iro rinozivikanwawo segirazi rinodzorwa nezuva remufirimu, rinoumbwa nekuputira simbi kana firimu remubatanidzwa pane yepamusoro-mhando yegirazi inoyangarara pamusoro nevacuum magnetron sputtering.Basa guru remufirimu ndere kudzora kuratidzira, kutapurirana uye kutorwa kwemwaranzi yezuva zvakananga, muchinangwa chekugadzira inodiwa kuratidzira ruvara.

Zvimiro zvegirazi rakavharidzirwa rinoratidza kupisa:

Dzora iyo inouya yakananga solar radiation zvakananga, yakanakisa mumvuri maitiro.

Yakanakisa inoratidzira ruvara uye yakanakisa yekushongedza mhedzisiro.

Kuvanza kwakanaka kwechinhu chemukati uye zvikamu zvekuvaka.

Ideal inooneka light transmission reshiyo uye reflection reshiyo.

Kuderedza kutapurirana kwechiedza che ultraviolet.
