Did anyone noticed that when you shoot the laser to a wall (5m away) the dot of this 445nm LD is a small rectangle which has the long sides looking up and down and short sides looking sides

however if you check that rectangle at a closer distance (about 1m) it makes a quarter turn(90degrees) and long sides looking at sides.
