Making laser tag with real lasers

As a compromise, I'd suggest using either green or yellow light since the peak sensitivity of the human eye is at the green center of the visible spectrum.

Okay. I'll look into green lasers.

(i.e. a lens; a fresnel comes to mind as it's less bulky than a regular lens)

Thought about this for a while but I don't know much about lenses.

@anon35827816

rather sensitive to mechanical damage

What about those plastic flexible ones?

@anon35827816

simple visibility tests

I want to be able to see the beam rather than just the dot. How much power does that require?

@anon35827816

"an opamp"

I knew that

Thank you for your help.
