New to stock at Crystran — ZnS Multispectral windows with AR/DLC coating for the 7–14 µm range.
Designed for demanding infrared applications where both transmission and durability matter, these polished ZnS windows combine:
• Excellent IR transmission across the LWIR band
• Anti-reflection performance in the 7–14 µm range
• DLC coating for improved durability and environmental resistance
These windows may also offer a practical alternative to Germanium AR/DLC coated windows for some infrared applications.
Now available from stock in:
• 40 mm x 3 mm - https://bit.ly/4tkK1gD
• 50 mm x 3 mm - https://bit.ly/4uvtS95
Ideal for thermal imaging, UAV payloads, defence, and harsh-environment IR systems.

With Germanium supply becoming more challenging, many IR system designers are exploring alternative materials.
