Zinc Sulfide (ZnS)

Broadband infrared material for multispectral optics and robust windows.

Material Introduction

Zinc Sulfide is widely used for multispectral optical systems where visible-to-IR coverage and environmental durability are both important.

Optical Performance
MetricTypical Value
Transmission Range0.4 - 14 um
Refractive Index (10 um)~2.20
Common GradeCleartran / multispectral
Applications
  • Multispectral imaging windows
  • Aerospace and defense sensors
  • Ruggedized IR viewing ports
Comparison Notes

Compared with ZnSe, ZnS often provides broader spectral usability in visible-to-IR systems while maintaining good mechanical strength for field applications.
