【Abstract】 This paper introduces the selection of long-wave-pass and short-wave-pass edgeinterference filters.The characteristics of the pass bands and stop bands of the edgefilters have been calculated.The methods of inserting matching layers have been adop-ted so that the transmittance in pass bands with particular wavelengths is improved.Theprimary results obtained in the research are:for longwave-pass Edge filters,reflectance(R) is>99% at the stop band 530nm and transmittance(T)is>97% at the pass band1060nm;for short-wave-pass Edge filter,R is>99% at the stop band 1060nm and Tis>97% at pass band 530nm.更多还原
