自从1939年蔡司厂生产出第一批滤光片以来,金属干涉滤光片的应用已深入到科学技术各个领域。在通常情况下,干涉滤光片用来滤出一束连续光的单色光。如果不是对透过的光的单色性有很高的要求的话,它是分光计的一种简单、廉价的代用品。此外,与通常使用的分光计相比,它还具有光强较大的优点。金属干涉滤光片是由几层在高真空中蒸镀上的介质层构成的,介质层的光学厚度为透过光的半波长的整数倍数。这些介质层的界面上 Since the first batch of filters were produced by Zeiss in 1939, the application of metal interference filters has been extended to all fields of science and technology. Under normal circumstances, interference filters are used to filter out a continuous light of monochromatic light. It is a simple, inexpensive alternative to a spectrometer if it is not very demanding on the monochromaticity of the transmitted light. In addition, compared with the commonly used spectrometer, it also has the advantage of greater light intensity. The metal interference filter consists of several dielectric layers deposited in high vacuum. The optical thickness of the dielectric layer is an integer multiple of the half wavelength of the transmitted light. The interface of these media layers
