If you have made a decision to make highly
precise dot generation at different work distances, even though it is far
enough to reach, not simply relying on simple green laser pointer or any other
manual dot projecting tool, it would be a much better solution for users to
operate a highly bright beam emitting device, such as a 532nm green laser diode
module. It keeps works with high brightness and highly visible green laser
light source generation. Under operation with the lowest laser beam divergence
and the special TEM00 lase...
