Abstract: Reflex devices preferably mounted on photographic or cinematographic apparatus with retractable mirrors which may be rotating, oscillating or moving are the more adapted to balancing because as they are lighter. The decrease in weight is achieved by using pure carbon, preferably in the form of vitrified carbon, for the support material of the mirror. The microscopic pores opened during the fine machining of the polished surface are eliminated by an additional vacuum treatment during manufacturing of the intermediate product composed of tridimensional cross link synthetic resine.
