Are Green Laser Sights Better Than Red

Red light waves range from 620 to 750 nanometers and green light ranges from 495 to 570 nanometers.

Are green laser sights better than red.

The number one reason to use a green laser is daytime visibility. Red is higher on the spectrum at 635 nanometers. Green can be used inside or out but green is much more visible outside and can be used to engage targets in similar circumstances. The eye s frequency response is bell curve shaped with the highest point of the curve being in the green while the red lies on the right end of the bell curve.

Green is close to the center of the visible light spectrum at about 532 nanometers. The human eye is better able to recognize colors in the green spectrum so a green laser is more visible under bright light conditions. From the target s point of view having a red laser dot on your chest is very impactful. Recently a green laser was introduced to the laser sight family.

You will have a much easier time seeing a green laser in broad daylight than red.
