With a 28º vertical field of view, the plano-convex lens doubles the standard lens’s 14º beamwidth. When used with the DIDSON Large Lens Set, it generates a 14º vertical beamwidth versus the usual 3.5º.  

Maximizing coverage and capture, the extended vertical area makes it easier to keep your target in the field of vision, minimizing the effect of tilt.

Fisheries applications use on the plano-convex Spreader Lens for imaging fish and capturing dynamic behavior, while law enforcement and military use it to improve the effectiveness of hull inspections.
