Browe BCO Tenebraex Killflash

The Tenebraex Anti-Reflection Device (ARD) was developed to camouflage reflections from riflescopes and binoculars optics,  it also works as a sun guard the benefit of blocking sun glare or reflections from getting inside the scope.  The 4x32 Tenebraex killFlash ARD was design to attach directly to the (M38x1) threaded objective housing on the 4x32 BCO. 

Tenebraex ARD works by clustering a large number tiny tubes into a honeycomb-like grid. The length-to-width ratio of these tubes has been selected based on the field of view of the 4x32 BCO.  With this unique geometry, there is no vignetting or reduction in the field-of-view, light reduction is only on the order of 15%, any loss in resolution is imperceptible... and glint is eliminated.
