Abstract

Abstract

This paper demonstrates the design and fabrication of the dual-band antireflection coating in 0.8-1.7 m and 3.7-4.8 m wavelength region at 0 incident angle on the ZnS substrate based on oxide materials. The choosing on evaporation materials, optical coating design and fabrication method, et al. are discussed in detail. The dual-band IR antireflection coating has been successfully produced by Plasma Ion Assisted Deposition(PIAD) technique on both side of the ZnS substrate. Transmittance and environment test results show that the average transmittance is larger than 95% during 0.8-1.6 m wavelength region and larger than 96% during 3.7-4.8 m wavelength region, respectively. The firm adhesion and good tribology ability have been obtained referring to the general specification for optical coatings.
