Zinc Sulfide (ZnS)

Zinc Sulfide (ZnS) crystals are widely used in optical and imaging applications due to their high transmission in the visible and infrared spectra (0.35 µm to 12 µm). ZnS has a cubic crystal structure and is known for its excellent optical clarity, low dispersion, and high refractive index. It is commonly used in optical windows, lenses, and prisms for infrared imaging, thermal cameras, and laser optics. ZnS also finds applications in night vision systems, thermal detectors, and scintillation detectors due to its good scintillation properties. Additionally, ZnS is used in high-energy laser systems and military applications where infrared transmission and durability are critical. Its resistance to abrasion and good chemical stability make it ideal for use in harsh environments.
