532nm laser pointer safety mechanism

You may not know that the green laser pointer with a frequency of 532 nm is a brighter color to the human eye. It is actually 5-7 times brighter than all other colors. This is why plants are green, because green absorbs the best light, and why green light seems to be visible under lower power light sources. Here, a 100mW green high powered laser can be seen for more than 5 miles at night. Other colors are very bright, but green is the highest level of visibility. No wonder the focused laser beam is used improperly. For this reason, high-quality units currently on the market use so-called infrared beam filters. The role of these safety mechanisms is actually to prevent the laser itself from emitting invisible light. This is important for all output power, but even more so for some combustion devices discovered today. This is because the beam is visible when using a visible laser, and reflection surfaces, experience, and potential unintentional exposure can be carefully avoided. This simple, cheap device that does not use cheap equipment is actually a bit dangerous when used at high power, indoors, and for long periods of time. Make sure that the laser system you are considering has an infrared filter to prevent unnecessary exposure.
