Hi All,
I am a complete novice when it comes to lasers, however I have come up with an idea that requires a laser and I thought someone here might be able to help me out.
I am looking for a small battery powered laser that can project a circle. The laser will be positioned around 1 meter from it's target surface and will need to project a circle of approximately 1 meter in diameter. The strength of the laser beam will not need to be overly high, though the projected circle must be visible on the target surface in direct sunlight. I live in Australia, so the laser must pass our laws as well.
I have read a bit about diffraction gratings and have done a heap of Googling, but I can't find what I'm looking for. It would be much appreciated if someone here could point me in the direction of a laser I can purchase.
