ZnS
Quantity : 999
ZnS is often used in the 8 to 12 microns region. Its high resistance to rain erosion and high-speed dust and particulate abrasion makes it particularly suitable for exterior IR windows on aircraft frames.
ZnS has a lower cost relative to ZnSe and ZnS MS, and has potential wherever a tough and strong IR transmitting material is required.
Key Features:
• Remarkable fracture strength and hardness.
• High resistance to erosion and abrasion.
• Flat, spherical, and aspherical manufacturing expertise.
• Grinding, polishing and shaping to > 80mm diameter.
• High performance, cost-effective ZnS fabrication.
• ZnS blanks and sheets available
