LaserMax: :
What’s the big deal about green lasers? Why is the US military converting to green lasers? How does the Uni-Green help my shooting? And how do those wizards at LaserMax do it, anyway?
First, some background:
Green and the Human Eye
Stars in the night sky might appear white, but actually they emit a lot of colors. Hot stars emit more blue light, and cooler stars emit more red. Our sun is medium temperature for a star. The sun emits more green than any other color (see diagram below).
In bright light, our eyes are capable of seeing rainbow colors from violet to red, with peak visibility in the green. In other words, our eyes are most sensitive to the color that is most available from sunlight: green.
Color Sensitivity and Ambient Light
Our eyes are roughly four times more sensitive to green than to red under bright lighting conditions (see visibility diagram). When we’re dark adapted the effect is even more pronounced.
Our eyes adapt rapidly to changing light conditions and most of the time we don’t even notice. Typical indoor lighting is actually very dim compared to a bright sunny day outdoors. Since our eyes are less sensitive to light when it is bright and more sensitive when the ambient is dim, the same laser will look dim in sunlight and bright indoors or dusk-to-dawn.
SWAT application; thank you for your service, gentlemen.
The shooter needs a color that works best in both bright light and dim light. This is the advantage of green. We can see it farther away (longer range) and under a wider variety of lighting conditions than we can with red. The advantage in an on-the-move shooting situation could make the critical difference in urban combat, whether for military or law enforcement applications.
That Pulsating LaserMax Beam
LaserMax goes another step further in providing a laser beam that is quickly acquired by the eye: the beam pulsates. Why? Our eyes are much more sensitive to flashing light than continuous or steady-on light. This fact has been well known for decades. It is the reason that emergency vehicles have flashers. The pulsating LaserMax beam means that a shooter can track muzzle position in his or her peripheral vision while scanning for multiple assailants. The pulsating also indicates that this green laser beam means business. .
Military application; thank you for your service, gentlemen.
So LaserMax provides the highest power allowed by law, delivers it in the color most easily seen by the eye in the widest variety of lighting conditions, and pulsates the beam for most rapid acquisition. All together, the LaserMax Uni-Green is the most visible laser aiming device allowed by law.
IT ISN’T EASY BEING GREEN!
Current diode laser technology does not give green light. LaserMax uses sophisticated techniques using multiple crystals, filters and other optical components to convert commercial laser diode output into green light in the smallest package commercially available.
SOME THINGS YOU SHOULD KNOW:
Eye safety: The fancy optical filters that we put in are expensive, but they are important! Green laser technology emits harmful infrared light that can damage the eye. LaserMax filters the infrared out so you (and anyone who is on the receiving end) is safe from eye damage. Buyer beware. Many manufacturers do not use filters.
Recoil: Green lasers are much more complicated to build than red, blue, or infrared. They can’t all take the recoil. Our Uni-Green has been live-fire tested with thousands of rounds on punishing weapons including AR-15s and shotguns. Buyer beware. Most green lasers are not built for live fire
Temperature: Green lasers are sensitive to temperature. Most will work between 50-70 degrees Fahrenheit. LaserMax uses proprietary technology to extend the range of operation to 40-100 degrees Fahrenheit, making the Uni-Green practical for temperate climates, home defense and indoor public spaces (law enforcement).
Power output: To compensate for temperature sensitivity, some manufacturers exceed the output power allowed by law. Even green light can damage the eyes if it is too bright. You can be assured that the LaserMax Uni-Green is completely eye safe and compliant with FDA regulations.
