Description
技术领域technical field
本发明涉及一种可用于空间环境的中性挡光片，属于薄膜技术领域。The invention relates to a neutral light-blocking sheet that can be used in a space environment, and belongs to the technical field of thin films.
背景技术Background technique
中性挡光片的作用是对通过它的光线强度进行衰减，这种衰减是中性衰减(非波长选择性衰减)，也就是对各种不同波长的光线的减弱能力是等同的(不同波长所对应的透光率的变化值是相同的)。中性挡光片在地面常规环境主要使用在摄影领域，主要作用是控制进光量、防止相机过度曝光等。随着空间技术的发展，中性挡光片将应用于空间技术，在空间环境下，要求中性挡光片透光率不随温度、辐照等环境条件而发生变化。The function of the neutral light blocking film is to attenuate the light intensity passing through it. This attenuation is neutral attenuation (non-wavelength selective attenuation), that is, the attenuation ability of light of various wavelengths is equal (different wavelengths The corresponding changes in light transmittance are the same). Neutral light blocking film is mainly used in the field of photography in the conventional environment on the ground. Its main function is to control the amount of light entering and prevent the camera from overexposure. With the development of space technology, neutral light barriers will be applied to space technology. In the space environment, the light transmittance of neutral light barriers is required not to change with environmental conditions such as temperature and radiation.
