Pulsar IR Flashlights’ spot can be smoothly adjusted from narrow beam to flood. Unfocused beam illuminates larger area; the narrow beam light ensures longest possible viewing distance. Power is adjusted by rotating the wheel on the body next to the ON button. Adjustment of both – power and spot divergence angle – helps achieve best illumination of an object in specific observation conditions. Design of Pulsar IR Flashlights allows spot position to be corrected in the field of view horizontally and vertically. To do this, loosen the ring fixing the optical assembly, adjust the IR spot in the center of the field of view (the NV unit should be on) and tighten the ring again. Pulsar IR Flashlights are equipped with a mount adaptable for Weaver rail available in most modern night vision rifle scopes and optical units, as well as hunting or sports and pneumatic weapons. Package also includes an adapter that allows flashlights to be attached to NV units outfitted with a ¼ inch tripod mount.
