This Demonstration shows a beam from a laser incident on a convex-plane lens, producing two reflected beams. Use the sliders to control the alignment of the three beams. The alignment is perfect when the incident beam and the two reflected beams overlap completely. This will be accompanied by the message "alignment is optimal."
