Umarex introduces the Long Distance Illuminator (LDI) within a new brand called Optical Dynamics. The first light offered is an Optical Dynamics 40mm or OD40. Its technology incorporates the use of a patented optic aperture and camera-quality lens configuration called CALS, which stands for Collimated Amplified Lens System. This set of lenses captures the image of light produced by a CREE LED, magnifies that image and focuses it to create a true collimated “gin-clear” light that originates from an LED. It serves a variety of applications, including for search and rescue teams, firefighters and utility linesmen.
