The durability and proven transmission stability of our patented reinforced polymer is the cornerstone of the CAP Series. Traditional round crystal infrared (IR) windows are made in 2” – 4” diameters. This is primarily because increasing the diameter and maintaining the thickness exponentially increases the fragility of the crystal, making larger sizes weaker and cost prohibitive.

The CAP-C offers locking covers for your IR window. These are useful in areas of high traffic and
protect the IR viewing panes from impacts, flying debris and dust.
