Single-Source Design, Engineering & Manufacturing

Seamark designs, engineers, and manufactures optical laminates and POS scanner windows under one roof. For engineers, that means tighter tolerances and faster design iterations. For procurement, it means a simplified supply chain with a single point of contact from prototype to production.

Choose the Right Substrate for Your Application

We work with a range of proven optical materials, matched to your performance requirements and budget:

• Sapphire — Rated 9 on the Mohs hardness scale, second only to diamond. The standard for high-abrasion, high-cycle environments where window failure directly impacts uptime.
• Quartz — Excellent optical transmission with strong thermal and chemical resistance, ideal for industrial and semiconductor process environments.
• Gorilla Glass™ & Coated Alternatives — Cost-effective scratch resistance for less demanding applications, protecting equipment without overengineering the solution.

Built to Last — Guaranteed

Our scratch-proof windows carry a lifetime guarantee. Scratch-resistant windows carry a limited lifetime warranty. It’s a straightforward commitment to quality that reduces your total cost of ownership and simplifies warranty management on finished equipment.
