Diameter Laser

Hi to everyone,

i'm realizing a didactical project in the way of Laser Game.

I have realized all sw part of it, and now i'm dealing with some other hardware problem.

In my arduino, i have one IR receiver hit by a simple commercial laser (it is the gun of the game).
The two components work perfectly togheter, but now i want to expand the diameter of the laser in order to increase the coverage of the gun. (Increasing the diameter of the commercial laser, it will be simplier to hit the IR receiver).

Is there any solution?

Use infrared LED as the emitter instead of a laser. Commercial "Laser tag/Laser games" use modulated infrared LEDs.

// Per.

IR LEDs are available in various opening angles.

Is there any solution?

Use a lense.
