Green is the most obvious color because its entire beam can be seen by the human eye. However, users should be careful not to look directly at the laser. Otherwise, they may cause eye damage. Keep safety precautions in mind, green laser pointer are practical and fun. In addition to the laser Pointers, pilots faced another problem: The Christmas laser lights were designed to decorate the exterior walls of houses. The gadgets carry warnings to prevent them from projecting lights onto or near the flight path of aircraft within 10 nautical miles of the airport. If the user's desired lighting area is within this radius, the user is asked to reduce the Angle of the light so that the laser does not point skyward. First of all, I have to say that the most common symptom you see after being hit in the eye with a laser pointer is blindness. It's not permanent damage and there's probably nothing to worry about. It's just your eye's reaction to something very bright reaching your eye, like when you're walking outside and the sun is brighter than it is inside. Or, accidentally leaving the flash on the camera while taking a picture of yourself.
The laser designator has become more popular with astronomy enthusiasts. Astronomers around the world are adding high-powered lasers to their toolboxes. So we took the time to provide some guidance for safe use of laser Pointers. Green lasers are very popular these days, especially among astronomers and astronomers. The green high powered laser emits light at 532 nanometers, while the red laser emits light at 630 nanometers. Visual fault speakers are essentially high power lasers. These lasers are then connected to optical fibers and used to quickly identify faults or weak areas in fiber optic cables. These zones can be anything from cracks and holes to slight bends and strains; Even the smallest flaw in fiber optic cables can be a problem.
