Determine the application of the laser pointer
Laboratory analysis and other general application instruments. Class II: low-power visible laser (power 0.4 mW-1 mW), eye-closed reaction time 0.25 seconds. Use this time to calculate exposure values. You cannot exceed the error limit. The green laser pointer acts as a microphone. Lasers less than 1 mW usually cause dizziness, but do not. First and foremost is the clear application you need. Low power red, blue and green laser pointer are commonly used in classroom presentations, lectures, lectures, PowerPoints and business meetings where a laser pointer with a short visible laser beam is sufficient. Green laser pointers in the 50mW to 150mW range are always very popular in astronomy. Visible and bright laser beams ahead are useful for astronomy researchers, astronomy enthusiasts, sky and star demonstrations. On the other hand, high-power red-blue-green laser pointers are mainly used in military battlefields, scientific research, medical treatment, and entertainment activities such as shooting and thermal experiments. Closing and protecting your eyes is not completely safe. Be careful when going directly into the beam. Others are lasers to far avoid protection class II observation. Typical applications include classroom presentations, 5mW laser pointers, sights, rangefinders, and more.

Technology
A laser pointer is a device that emits laser light. According to the different working medium, it is divided into four types: gas laser, solid-state laser, semiconductor laser and dye high power laser pointer. The introduction of green laser pointers greatly reduces the production cost of modules. High-power laser pointers Popular stores A portable pen type, not only the best choice for lighting, but also for many business trips in conference presentations, seminars, study groups, etc. Best for people. Blue Light This is my first time using a powerful laser, but I like it because it's bright. I love how cool it looks and the fit when I hold it in my hand. Although it is a multi-function pointer, it is easy to set up and has good operability. The button is easy to press, and it will not feel tired after a long time. It can also instantly light a match, knock back glass, break balloons, light cigarettes, and light firecrackers. In recent years, free electronic laser pointers have also been discovered. The outlet of the super laser pointer is mostly pulse type.
