Laser Genetics ND 3P Green Laser Weapon Light ND3P

Green light is the most visible to the human eye and requires the least amount of eye adjustment at night. An eye that has adapted to daytime conditions generally has a maximum sensitivity around 555nm. Compared to the color red which optical spectrum is around 630 – 650nm our eye is closer to the Green region of the optical spectrum at 510 - 530nm MFR # ND3P UPC: 793676044088 The ND3-P Laser Designator uses advanced green laser technology to create true night vision and turns a scoped rifle into a night hunter. The patented Rotary Optical Collimator uses a system of 9 fully multi-coated lenses that allows full adjustment and control of beam diameter and intensity to focus light where it is needed most. Rotating the collimator ring to minimum creates a bright micro beam of green laser light visible up to 3 miles. Rotating the collimator to more open settings provides plenty of illumination to light a trail at night or paint a target at up to 250 yards. Battery life allows it to handle any emergency with over 7 hours of continuous use (3 hours of continuous use at 0˚F).
