高性能的新式夜间望远镜美国制造了一种“J221”型通用夜间望远镜。它不是利用红外线,而是用光线增值的原理,制造特殊的透镜,能把月光或星光下景物的微弱反射光,增强五万倍,从而使人的眼睛看清楚它。这种夜光镜除用作观察外,还可配在枪上作夜间瞄准用,也可装在照相机、录象机及电影摄影机上,进行夜间拍摄用,而不需附加任何照明设备。这种夜光镜尚有多种形式,适合于夜间驾驶或航海使用。
High-performance new nighttime telescope The United States made a “J221” type universal nighttime telescope. Instead of using infrared rays, it uses the principle of increasing light to create special lenses that enhance the faint reflections of moonshine or starlight objects by 50,000 times, making the human eye see it clearly. In addition to this luminous mirror used for observation, but also can be used on the gun for night targeting, can also be mounted on cameras, video cameras and movie cameras for night shooting, without the need for any additional lighting equipment. There are many forms of this luminous mirror, suitable for night driving or sailing.
