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 zero degrees 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 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.
The compact ND-3 Laser Designator - The Ultimate Alternative to Night Vision.
Brilliant source of illumination for Law Enforcement or various Military applications.
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 rough and cold weather conditions in temperatures of 40° F. 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?
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.
