Title (EN) MIRROR REFLEX SYSTEM
(FR) SYSTEME REFLEX A MIROIR
Abstract: front page image
(EN)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.
(FR)Des dispositifs reflex de preference sur des appareils photographiques ou cinematographiques avec des miroirs escamotables qui peuvent etre tournants, oscillants ou mobiles se pretent d"autant mieux a equilibrage qu"ils sont plus legers. La diminution du poids est realisee grace a l"emploi de carbone pur, de preference sous forme de carbone vitrifie, pour le materiel support du miroir. Les pores microscopiques mis a nus lors de l"usinage fin de la surface polie sont elimines par un traitement supplementaire sous vide lors de la fabrication du produit intermediaire constitue par de la resine synthetique a reticulation tri-dimensionnelle.
