Im looking for the best 5mW green laser I can buy, preferably one with lens kit to project lines, circles etc...?
Also is there any possible way to make a thicker line then the usual thin line that a laser creates?
Does adding a HDG reduce the power of a laser?
If so, if I wanted to project a shape but wanted to keep it safe <5mW could I increase the power of the laser because of the HDG?
I'm looking for two helpful tips please. I'm currently looking at designing a new kids activity toy featuring lasers. So my questions...
1. What lasers will work during the day (and night)?
2. What level of laser is child safe/eye safe?
I'd appreciate your help.
Thank you.
