【摘要】 当前近红外滤光片在军用，数码影像方面，光学全息和光电技术中应用非常广泛，因此其具有广阔的市场和应用前景。尤其是红外截止滤光片已经成为数码产品不可或缺的重要组成部分，它的性能直接影响数码成像的质量。 本文通过简单地介绍红外截止滤光片在数码影像产品中的作用及工作原理，引出了红外截止滤光膜的研究目的和意义。要实现红外截止滤光片在高良品率下的量产，就需要优秀的膜系设计和和生产工艺予以保证。本文结合具体的膜系详细地阐述了薄膜的基本原理，着重讨论在现有特定的生产条件下，如何通过相关理论，根据材料的特性及薄膜的应用条件而选择合适的材料，并计算材料的实际折射率，进行红外截止滤光膜的膜系设计。对薄膜的厚度均匀性分布规律进行理论分析。对半波孔的消除，工具因子制备工艺过程，以及对影响薄膜光学稳定性的因素进行讨论，筛选出影响光学稳定性的主要因素重点分析，最终得出解决该问题的方法。更多还原

【Abstract】 The Near Infrared Filter is widely used in military affairs, digital figure, optical holography and photoelectric technology at present. So it has both wide market and foreground. Especialy, the IR-cut filter is indispensably important part of digital produces. And its capability affect the quality of digital image straightway.From introducing its function in digital figure produces and theory. This paper fetch out researchful intention and significance about the Infrared-cut Filter. In order to produce IR-cut filter with large quantity and high quality, we need excellent film design and perfect production technology. Under existing specific production condition this paper discuss emphatically that how to select suitable material according to the property of material and the application condition of film, by related theory. And compute the real refractive index of material. As emphasis, the paper introduces coating design, theoretical analysis for the thickness uniformity distribution law, half-wave hole elimination, tooling, deposition process ,At the same time, we discuss for the factors that affect film optical stability, screen the major factor key analysis that affects optical stability, and get the method of solving this problem eventually.更多还原
