IR Laser Diodes
« on: August 27, 2018, 10:28:31 AM »
Hi all,
Im thinking to improve my Laser tag system which is based on tsal6100 and lenses into laser diodes:

by the way, already got good signal @ distance up to 100 meters

any advice ?!

Be very careful with laser diodes that claim their output is only 1mw, and using laser diodes with any higher output than that can cause eye damage if you're not careful.  There was a finding by an independent company that many of the laser pointers sold on Amazon were actually outputting much higher power than advertised (http://laserpointersafety.com/illegalpointers/illegalpointers.html). 

While the idea of a more challenging game is appealing, it also comes with some drawbacks.  The size of the laser at range may be much smaller than an IR LED, but that just means you'll need a few more sensors on the players body to maintain that realism.  That gets to be a pain. 

The range will be much improved, but that would only be most useful for games where you're valuing sniping from long distances.  When you're dealing with large ranges, people are more spread out, and you need many more people to have an energetic game.  If you're looking for the more long and drawn-out type game-play more typical of airsoft, then laser diodes might be the way to go.  Again, just watch out for safety.  Make sure you test the output of your diodes.
