Various discussions about laser pointers


There are different types of high power laser pointer on the market, so people should always have a clear observation and sufficient basic knowledge before making a decision. For laser enthusiasts, choosing a laser pointer from a reliable supplier and knowing what type of application you need is always a wonderful choice. Please be careful and use a satisfactory laser pointer according to your needs.

What should I do if the laser pointer enters the eyes?

Along the beam, a luminous source 30 meters away, a laser pointer fixed on the wheel of an electric vehicle, was found. Although the light is shining diagonally upwards, because the laser pointer is fixed too low, pedestrians will almost always be irradiated when they pass by the booth. The other laser pointer fixed on the electric vehicle projects a green spot of light on the ground downward. Laser pointer: Never shoot the eyes directly. The real name of the laser pointer is the "laser pointer". It is a light-emitting diode emitter designed to be easy to carry with visible light. It is usually used in adult reporting, teaching and other occasions. But because children are naturally curious about light, at the same time, laser pointers are cheap and colorful, many children like to take this photo to take photos, and even parents buy them to play with. 3w laser pointer damage to children's eyes may occur within a few seconds of direct exposure, and may cause long-term damage to the eyes.

What does MW in laser mean?

The mW value is the unit of measurement for the light output of the laser pointer. This value usually does not correspond to the actual light output measured in candela/square meter [Cd / m²], but more is the output provided to the laser diode in the form of electricity. Due to the loss of efficiency, the light output is significantly lower than the electrical output. Chinese laser 20000mw with a power exceeding 200mW are becoming more and more common in Germany (mainly illegal). With such high performance, it is! still! There is hardly any heat transfer, but not only points, but also the light beams are already visible even during the day. It works well, but it is very dangerous!
