摘　　要：介绍了一种截止带非常宽的近红外耐久滤光片的设计制作方法。采用了 Si、Si O2 做薄膜材料 ,利用中心波长不同的两个短波通滤光片对接 ,实现了很宽的截止带。分析了膜系设计的一些细节。掌握了材料 Si的蒸发方法。A durable interference filter with wide blocking band for the IR region is shown. The filter consists of Si and SiO 2 layers on K9 glass. Connecting two short wave pass filter at different center wavelength, resulted with a lager blocking spectral region. Some details of film design have been discussed. The technology of depositing Si material has been handled.
