Do you know laser pointer with different tips?
Perhaps the most well-known laser pointer is its use during demonstrations. For this reason, the laser pointer is small, easy to carry, and relatively affordable. Most laser pointers used for presentations have a red beam and low wattage, so they can be used safely indoors. People prefer to use a Laser pointer because it makes it easier to highlight information on the screen. It also allows the presenter to maintain a professional stance. This is because excessive movement during the presentation will distract the audience. The use of laser pointers during the demonstration is also useful for disabled persons with limited mobility.

You may not know that the green laser with a frequency of 532nm is by far the brightest color in the human eye. It is actually 5-7 times brighter than all other colors. This is why plant life is green, because green absorbs the best light, which is why green light can be seen even at lower power. Here, you can see a 100mW green laser for more than 5 miles in a clear line of sight at night. Other colors are also very bright, but green is the highest visibility. Many people do not know that the cheapest laser pointer on the market does not have an IR (infrared) filter. This means that they are inherently more dangerous because they emit invisible infrared light, which can be harmful if exposed for a long time. Make sure that every laser you consider, whether high-power or low-power, contains an infrared filter to ensure you get the safest beam.
