| Abstract: | In order to meet the special requirements of infrared military equipment,an infrared double waveband filter film system was designed according to the theory of thin film and an infrared dual-band filter membrane with a high reflection at 1 064 nm and a high antireflection in 3~5 μm was produced on a multi-spectral ZnS substrate by adjusting process parameters and using electron beam vacuum deposition.With ion bombardment of low energy and vacuum annealing,the anti-damage threshold of thin film was improved.Furthermore,the stress between the film layer and the substrate was reduced to 51 MPa from 122 MPa measured by the BGS 6341 stress tester with gradient method.This film meets the requirements of infrared military equipment. |
