N—1型鼓轮式高速摄影机是根据科学院力学所研制的脉冲He—Ne激光光源配套使用要求而设计的。摄影机采用鼓轮内表面装片形式,用35mm底片;鼓轮外径为500mm用等强度原理设计;鼓轮由电机直接带动,用光电测速,画幅尺寸为8×22mm~2时摄影频率可达4000幅/秒;摄影物镜与DF照相镜物镜通用,可换用f’=58mm,105mm,135mm;取景放大镜为5×;装卸底片用特殊设计的装片门及可拆卸暗袋。
N-1 drum-type high speed camera is based on the Institute of Mechanics developed pulse He-Ne laser light source supporting the use of design requirements. The camera uses the inner surface of the drum film loading form, with 35mm film; drum outer diameter of 500mm with the principle of equal strength design; drum directly driven by the motor, the photoelectric speed, frame size of 8 × 22mm ~ 2 when the photographic frequency up 4000 / sec; photographic objective lens and DF photographic lens common, can be replaced with f ’= 58mm, 105mm, 135mm; framing magnifying glass for 5 ×; loading and unloading film with a specially designed loading door and removable bag.
