Optical Filter Systems

Professional protection from threats across the visible and non-visible spectrum. 

Tenebræx® Optical Filter Systems help defend your personnel from threats across the visible and non-visible spectrum, while shielding against glint, glare and making detection by retroflection nearly impossible.

 

All Tenebræx® Optical Filter Systems consist of a Tenebræx® optical filter (OF), and a killFlash® anti-reflection device (ARD).

 

Protection begins with design. Tenebræx® OFs are built to survive, contained between two layers of optically correct glass for clarity, protection and long service life. 

 

Engineered with a precise degree of tilt during construction; this tilt is angled down and away from the eye of the operator, aiding in dissipation of the signal directed at the optical device the Tenebræx® OF is installed on and into the included killFlash® ARD, making retroflection nearly impossible to detect by removing mission killing glint.

For over 20 years, Tenebræx® has provided OF Systems to the military and police services, with a history of custom applications and designs available for professional applications.
