Hi,

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?

Hi nikosb!

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

Dear nikosb,

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. :mad:
And here the laser is available, but the laser class of this laser is too high. :mad:
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!
