That's the sort of information that should have been in the first post! (Well, OK, maybe I should have followed your original link and read all the specs...) A laser distance sensor weighing 800g, 5" in size and costing multithousands of dollars, that needs to operate in a harsh vibrating industrial environment?
You are way outside the abilities of a cheap hobby servo pan/tilt bracket!!
What distance will it be measuring? It has a 350 metre range, even a small amount of vibration is going to cause major misalignment with the target.
You are going to need a large metal pan/tilt device with vibration damping etc etc. It's going to get big and expensive!
