Chiyambi cha Kupanga

Magalasi a PC space amapangidwa ndi magalasi a polycarbonate, ndipo magalasi wamba a resin (CR-39) ali ndi kusiyana kwakukulu! PC imadziwika kuti galasi loteteza zipolopolo, kotero magalasi a PC omwe amatsatira makhalidwe abwino a zinthu zopangira kukana kwambiri kukhudza, ndipo chifukwa cha refractive index yayikulu komanso kulemera kopepuka, amachepetsa kwambiri kulemera kwa lensi, pali zabwino zambiri monga: Chitetezo cha UV 100%, zaka 3-5 sizidzakhala zachikasu. Ngati palibe vuto mu ndondomekoyi, kulemera kwake kumakhala kopepuka ndi 37% kuposa pepala wamba la resin, ndipo kukana kukhudza kumakhala kokwera nthawi 12 kuposa resin wamba!
