laserpointer seller search

[lupo2222]

Hello dear.


I'm looking for a laser pointer to align so-called directional radio antennas. The beam should also be visible during the day. So I wanted to ask you where I could reliably order such a laser pointer.
Is a green laser pointer with 50 watts still realistic?

50 milliwatts perhaps, not 50 watts...

You say that you want to order a laser pointer but I doubt a handheld device would be helpful for aligning radio antennae, but I don't have much knowledge in that field. A 50-watt green laser is not just something you can buy online, from what I can gather, lasers of that size are usually DIY projects by skilled hobbyists. If you are using the laser similarly to adaptive optics in telescopes, you need reasonably low divergence, making your task even harder to pull off.

If this is something you are actually going to try, good luck.
