Lens Design Problem

  1. Jul 13, 2010 #1
    I'm designing a flashlight using a new LED reflector. It creates a good spot, but I want it to flood on the edges. See image below. My thought was to create a lens and put it in front of the LED reflector to disperse the light around the edges. Can anyone point me to some simple tools that will help me design the lens?
