So, my previous post seemed quite benign: shine some light and observe the diffraction angles. Except one of the lasers, the purple one, is 25mW…! The green and the red are both at a much lower power level.
The output power of the purple laser, allows for the next two peaks in the diffraction pattern to be observed, but it comes at a price: you HAVE to wear protective glasses, because the energy in reflections will be enough to cause permanent damage to your eyes..!
And as you can see, there are many reflections..
Lasers are really fun, but the point here is: be careful. You can’t always predict what will happen 🙂☝🏻🚨
Proper protection glasses can be a lot more expensive than the lasers themselves but if you want to play with lasers, this is a place where you don’t want to save the money ☝🏻
