| 摘 要： | The transmittance characteristics of ZnS ceramics with infrared (IR) (3-5 and 8-12μm) antireflective coatings are studied. The film designs are optimized with programmed software. A double-side and double-layer scheme is employed. Two different double-layers with proper pa ameters are coated onto each side of a ZnS substrate. The measurement methods for transmittance are investigated. The measured transmittance for IR (3-5 and 8-12μm) surpasses 70%.
