Laser Genetics ND 3P Green Laser Weapon Light ND3P

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). 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.
