生产符合军事标准的近红外滤光片,关键在于使用经过筛选的近红外吸收染料,因为并非所有的近红外吸收染料都能满足需要。为了满足夜视兼容性的要求,近红外吸收剂可以单独使用,也可配合使用,还可以与普通塑料用染料混合使用,目的使其光谱幅亮度NR值符合-1.0E+00≤ NR ≤ 1.7E-10,色度要达到夜视颜色要求(夜视绿A,夜视绿B,夜视红,夜视白),可见光的透过率不低于20%。
English Version: Functional Dyes:Infrared absorbing dyes IR absorbing dyes is more often used for safty consideration. It can absorb certain wavelength of the IR lights. Our λmax is from 916nm(the maximum absorption peak).
Application: for location tracking, security, protection goggles, etc.
