Custom CVD ZnS IR Dome Lens – High Hardness 7.5-14µm LWIR Thermal Imaging Optics

Key Features & Benefits

• Superior Mechanical Strength & Impact Resistance:
  Features a high Knoop hardness of ~150, significantly surpassing ZnSe. Built to withstand high-speed flight, abrasive sandstorms, and rain erosion. (Ideal for integrating with DLC or Hard Diamond coatings to maximize durability).

•  High LWIR Transmittance:
  Maintains excellent optical transparency across the 7.5-14µm long-wave infrared (LWIR) band. Uncoated transmittance ≥70%, and up to ≥90% with AR (Anti-Reflection) coating.

•  Extreme Thermal Stability:
  Capable of operating reliably in a wide temperature range (tested from -40°C to 600°C). Perfect for high-temperature furnaces, aerospace rapid flight, and harsh industrial monitoring.

•  Full Customization & Coating Services:
  Fully customizable in size (diameter, radius, thickness), shape (hemispherical/spherical, flat to hemispherical transition), and surface quality (60/40, 40/20, 20/10). We provide standard AR, Hard Diamond (HD), and DLC (Diamond-Like Carbon) coatings to meet specific application needs.

•  High Purity & Low Scattering:
  Made from 99.9% high-purity CVD ZnS, ensuring uniform material composition, low absorption, and minimal scatter for superior stable optical performance.
