光学膜层种类繁多,广泛应用于光学和光电仪器中。在军用领域里,光学膜层的作用也相当突出,几乎所有的军用光学、光电仪器都要用光学膜层,如:用于减少光学系统反射的减反射膜;用于消除光学系统霜雾的导电膜;用于获得单色光的滤光膜;用于激光器偏振的偏振膜等等。它们对改善和提高光电仪器的有关战技指标起到了重要的作用。
A wide variety of optical films are widely used in optical and optoelectronic instruments. In the military field, the role of optical film is also very prominent, almost all military optics, optoelectronic instruments should use optical film, such as: to reduce the reflection of the optical system anti-reflection film; used to eliminate the frost fog of the optical system Conductive film; filter film for obtaining monochromatic light; polarizing film for laser polarization, etc. They have played an important role in improving and improving the relevant technical indicators of optoelectronic instruments.
