The ability to remain undetected is paramount to survival and mission success.

Today, no military force would think of going into the field without camouflaging their troops and equipment. Modern camouflage has made detection of equipment or the human form far more difficult. Being detected because of reflections has resulted in the loss of personnel, the failure of missions, and even changed the course of battles.

ARDs (Anti-Reflection Devices) use a high-tech honeycomb material and unique geometry to provide a low-cost practical way to hide reflections from optical surfaces. Tenebræx’s ARDs are used by U.S. Army, Navy, Marines and Special Forces.

Historical Overview

Tenebræx was founded in 1992. This company is based on a patented technology using a method to hide reflections from optical devices.

Reflections being seen by an enemy have determined the outcome of many famous battles and skirmishes, including the battle for Henderson Airfield in the Battle of Guadalcanal, the Carlos Hathcock—NVA sniper duel during the Vietnam war, the Zaitsev-Koning sniper duel in the Battle of Stalingrad, and the battle of Little Round top at Gettysburg (reflections from equipment). Moshe Dayan, the Israeli general, got his famous eye patch when a sniper saw reflection of the sun from his binoculars.
