(720 ILCS 5/2-10.2)
Laser or laser device.
"Laser" or "laser device" means
any small or hand-held battery powered device which converts incident
electromagnetic radiation of mixed frequencies to one or more discrete
frequencies of highly amplified and coherent visible radiation or light.
Proof that a particular device casts a small red dot or other similar small
and discrete image or small and discrete visual signal upon a target surface
at least 15 feet away creates a rebuttable presumption that the device is a
laser. Flashlights and similar lamps, lanterns, lights, and penlights are
not laser devices.
