Hello.
I've all but finished building a glove based laser tag emitter for my youngsters, and have got stuck on one of the last hurdles.
I want to have the IR LED housed in a small box or tube that would be positioned on the back of the glove, but still be small enough so that the size doesn't make it flop about.
If I use a 3mm or 5mm IR LED, with a lens that is no wider than 10mm-15mm diameter, and the overall tube housing the parts is circa 20mm x 45mm, is that decent enough to achieve an IR beam spread of about 6-8 inches at a maximum range of 6 to 8 metres outside, in an enclosed mostly wooded garden with fairly tall overhanging branches?
