There appear to be many different specifications for beam pointing. What are these and what do they mean?

Pointing Accuracy, Bore Sighting, and Static Alignment all refer to how well the laser beam is aligned to the housing of the laser. All lasers inherently have an associated tolerance for alignment (pointing) accuracy. Pointing Accuracy is a measure of the angular difference between the propagating axis (where the laser light is pointing) and the mechanical axis (where the housing is pointing). The application typically requires the user to make sure that the mount has the adjustment to take some of those tolerances into consideration. Pointing Stability is how much the beam alignment changes over a period of time. These specifications are very important for aligning and positioning a laser.
