Problems you may encounter with a nanoScan
scanning-slit beam profiler are due to either scanhead
damage, or out-of-tolerance conditions.
Scanhead damage can be categorized into two main
types; Laser and Mechanical. Laser damage is the most
prevalent, and results from exposure to lasers with
excessive laser power/energy density, and or high
average power. the damage can be classified into 2
categories, designated “Instantaneous” and “Long-term”.
