Need a powerful laser pointer
We need a powerful laser enclosure. I see flashlights everywhere on the Internet. The one I use here is what I bought from dealextreme in China. The laser diode can be found on e-bay, and I made two pointers here. One has 445nm blue and 405nm ultraviolet light. Since the driver I plan to use can handle a variety of diodes, you can choose the diode that suits you. A green laser pointer diode must be installed and equipped with a lens. The easiest way is to buy a lens mount.

Laser is an acronym for amplifying light through stimulated radiation, and it is an extremely bright light source. A 1mW visible high powered laser is about 1 million times brighter than a 100-watt bulb. Under certain conditions, this light can cause eye damage. Lasers are divided into four main categories to identify the risks associated with them. Level 1 represents the least dangerous situation. Exposure of the eyes to direct or reflected beams will not cause any damage. The output power of Class 2 laser is as high as 1mW, and it will not hurt the eyes when the exposure time is less than 250 milliseconds. This is usually because it needs to react to bright light sources and close your eyes (blink reflection). Class 3 lasers are divided into Class 3A (output <5 mW) and Class 3B (output> 5 mW). Class 3 and 4 lasers can cause damage to the eyes in a shorter period of time than the reflection of blinking. Therefore, as part of the university’s laser safety program, Class 3B and Class 4 lasers are strictly controlled.
