Described in the laser beam radius gloves cheap green almost imperceptible (a slight change in size is I keep both and pull 1/15 shutter speed), the AC store increasing distance laser sensor is quite popular as the theme. Here's a shop Wholesale Laser Pointer name Kitlaser, and I learned about the laser sensor from the United States (which, in the case of a disassembly, hangs a resistance divider that sinks 5V AC). The divergence increases the diameter of the distance of the laser beam from any plane of the beam at the intersection of the beam.
