NS•300 SubZero Long Distance Laser Designator

NS•300 SubZero 綠光鐳射瞄準儀

The new brighter, more powerful, ultra compact laser designator. The perfect alternative to night vision scopes.
The ND-3 Subzero™ Laser Designator uses patented technology to create true night vision and turns your scoped rifle into a night hunter. Combining a powerful green laser diode and a precision optical collimator, the NS-300 Subzero™ pairs with your scope and allows you to cast a bright beam of green laser light to fully illuminate targets at up to 300 yards. Rotating the collimator ring to its minimum creates a bright micro beam of green laser light visible up to 3 miles and rotating the same collimator to a wider setting allows it to be used as a light source in close quarters or following a trail in conditions with low natural light. To create true night vision, the NS-300 Subzero™ Laser Designator uses the same patented green laser technology as the standard Ns-300® series. However, the Ns-300 Subzero™ Laser Designator operates at temperatures as low as 0°F without loss of power.
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.
