Now target acquisition and illumination at night can be achieved even in the coldest of temperatures. The new incredibly bright ND-3×50 Subzero™ Long Distance Laser Designator is the most powerful Laser Genetics product yet. Equipped with an innovative unique circuitry system that enables the DPSS 532nm green laser to operate at temperatures down to 0˚ Fahrenheit, without loss of power.
The patented Rotary Optical Collimator uses a system of 9 fully multi-coated lenses that allowing full adjustment and control of the beam diameter and intensity to focus light where you need it most. Rotating the collimator to minimum, it creates a bright intense beam of green laser light visible up to 3 miles. Rotating the collimator to a more open setting it provides plenty of illumination to light a trail at night or “paint a target” at up to 500 yards.
For the most extreme and cold weather conditions, with temperatures of 40 degrees and below, we recommend using this ND-3×50 Subzero™. However if you’re spending most of your time in warmer climates of 40 degrees Fahrenheit and above, then we recommend using the ND-5® Laser Illuminator or one of the standard ND-3® Series laser designators.
Research has proven that green light is the most visible to the human eye (See Chart) 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.
