Infrared imaging technology has become an essential tool across defense, security, industrial, scientific, and environmental monitoring applications. For systems operating in the long-wave infrared (LWIR) spectrum, particularly in the 8–12 micron atmospheric window, one of the most critical yet often overlooked components is the infrared window. Acting as the first line of protection for sensitive thermal sensors and cameras, the window must combine superior optical transmission with rugged mechanical durability, ensuring reliable performance in even the most demanding field conditions.

At Del Mar Photonics, we provide precision-engineered infrared windows designed specifically for LWIR cameras and thermal imagers. These windows are manufactured from high-quality zinc selenide (ZnSe), a material well-known for its excellent transmission in the 8–12 µm range while maintaining low bulk absorption. Each optic is carefully polished to optical standards, ensuring minimal distortion and maximum clarity of the infrared signal.

For outdoor and field-deployed systems, durability is a defining requirement. Conventional coatings can quickly degrade when exposed to dust, sand, rain, salt spray, and other environmental challenges. To address this, we offer advanced hard AR coatings optimized for infrared performance, combined with robust protective layers such as diamond-like carbon (DLC) or equivalent hard overcoats. This dual approach provides outstanding abrasion resistance, hydrophobicity, and environmental sealing, without compromising the high transmission required for thermal imaging applications.

Typical specifications include:
Material: ZnSe, diameter 80 mm, thickness 3 mm.
Spectral range: Optimized AR coating for 8–12 µm LWIR.
Coatings: AR coating on the inner surface; hard / DLC or equivalent durable coating on the outer surface.

Performance: Minimal attenuation, high durability, and resistance to humidity, temperature cycling, and field abrasion.

Applications of these LWIR windows extend across multiple sectors:
Defense & Security: Thermal imaging for surveillance, target acquisition, and situational awareness.
Industrial Monitoring: Process control, equipment inspection, and predictive maintenance.
Environmental & Scientific Research: Remote sensing, atmospheric studies, and climate monitoring.
Autonomous Systems: Drone-mounted thermal cameras and vehicle-integrated night vision systems.
What sets these windows apart is their ability to balance optical performance and mechanical robustness. By maintaining high transmission in the LWIR atmospheric window while surviving harsh deployment environments, they enable IR cameras to operate reliably where standard optics would fail.

By choosing an advanced LWIR infrared window solution, system designers and engineers ensure that their infrared cameras not only capture accurate data but also remain operational and reliable in the field. Whether for a prototype system or full-scale deployment, our team provides both custom engineering and scalable production, making us a trusted partner for cutting-edge infrared imaging technology.
