Notes: - The power density limitation applies to any surface that the beam hits. For Beam Cube, since the object plane is outside the instrument, focal spots of much higher power density
can be imaged as long as the power density limit on the optical surfaces is not exceeded.
- The BA500 will not resolve pulses of energy below 100mJ unless the pulse rate is high. If the energy deposited in 1/50th of a second exceeds 100mJ, then the unit will be able to
show the pulses even though the individual energies are below 100mJ. The same applies to the Beam Cube except the minimum is 20mJ.
- If the beam power or energy density on the entrance window exceeds specifications, the window can be removed and not used, assuming that the power and energy density on
the first beam splitter is below the damage threshold.
