cross laser with smaller beam spread?
I ordered and received a cross laser #1058 with ~60 degree cross spread. This laser is great, but the 60 degree spread is too much for my project. I am looking for the same size laser but with a much smaller spread. Is there a similar product that will produce a cross spread of only 5 to 10 degrees (anything less that 60 would be nice to know about)? That would allow a larger distance to form a reasonable size cross. Thank you...

Re: cross laser with smaller beam spread?
These laser modules use a diffraction grating to produce the cross pattern. Most have a pretty wide spread. You can use a mask or gobo mounted a bit in front of the lens to restrict the beam spread.
