AB - Infrared band is so wide that no detector can cover the whole range. In order to obtain relatively wide range of optical signals, multi-channel image-forming system which separates optical signal into several wavebands and images the signal on corresponding detectors is widely used. As an important optical element, dichroic filter is equipped in multi-channel image-forming system frequently to divide optical signal into different wavebands. One kind of infrared dichroic filter was designed and fabricated, the spectrum range covers from 1.6ॖm to 13 ॖm and the incidence angle is 45°. The spectral curve was measured by Perkin-Elemer infrared spectrometer. The average reflectance in 1.6 ॖm~2.2 ॖm was over 95% and the average transmittance in 9 ॖm~13 ॖm was more than 85%. After spectrum measurement and environment reliability experiment, it was found that the infrared dichroic filter was competent to space engineering application.
