    A second topic to follow are the maximum allowed power and energy densities of the sensor. The maximum ratings are given in the sensor spec-sheet. The PM100D can display the actual power or energy density for a known beam diameter. For high power or high energy beams a good efficiency can be reached to chose a detector that is about 20% - 30% larger than the beam diameter.
