ND•3 Subzero - Long Distance Laser Designator - The Ultimate Alternative to Night Vision
To create true night vision, the ND-3 Subzero™ Laser Designator uses the same patented green laser technology as the standard ND-3® series. However through innovative engineering and equipped with a unique circuitry enabling the DPSS 532nm green laser to now operate at temperatures as low as -18˚ C 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 needed most. Rotating the collimator ring to minimum creates a bright micro beam of green laser light visible up to 3 kilometers. Rotating the collimator to more open settings provides plenty of illumination to light a trail at night or “paint a target” at up to 220 meters.
Brilliant source of illumination for use in cold weather, marine or search and rescue operations
If you are a law enforcement or military professional who spends most of your time in warmer climates, such as 3 degrees Celsius or above, we recommend using the standard ND-5® or ND-3® Series. However if you are normally spending your time in rough and cold weather conditions in temperatures of 3˚ C. and below, and looking for a compact, light weight and reliable source of light, then look no further… … the ND-3 Subzero™ is your choice.
Why Green Laser?
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.
Animal eyes are intensely illuminated by green laser light and clearly visible at extended distances when viewed through optics. For optimum night vision for hunting, pair the ND3 with a high quality variable power scope having a 40mm or larger objective lens providing maximum light transmission. The included ND3 mounting system for 1” tubes provides full adjustment for windage and elevation for scope alignment. Additional mounts for binocular, spotting scopes and weaver rails are included.
