I am looking for a diffraction grating lense with an arrow shape like this one:
I believe these are common in laser pointers. I have looked on ebay but I haven't been able to find it. Does anybody know where I can find this or a similar arrow?
I also search for weeks for a green laser (or a diffraction grating) which produces an arrow as in your picture.
Especially my laser should belong to laser class 2 and not to a higher class (that is, the power should be at maximum 1 mW).
Did you find something?
Or can anyone else help me?
I ended up buying a cheap laser pointer that had 42 different tip designs and one of them was an arrow. I don't see it anymore on ebay but this is very similar one with 12 tip designs
Since your last message I tried a lot to find a green laser pointer which produces an arrow.
Unfortunately, I really cannot find one. Here a perfect laser is offered, but they are out of stock.
And here the laser is available, but the laser class of this laser is too high.
As said, my laser should belong to laser class 2 and not higher (the power has to be less than 1mW).
Can you give me some more information to your laser pointer (power, Company name, model name,…)?
I also would appreciate a lot the help of other people!
