Energy Sampling is available on all LaserStar Model 3931 right-angle focus heads. This feature
allows the user to measure the system’s pulse energy output, validate pulse-to-pulse
stability and gather statistical information for reporting purposes. The versatile power/
energy display also offers many on-board features including laser tuning, data logging,
graphing, normalizing, power or energy density units, attenuation scaling, max. and min.
limits. All displays offer digital or analog needle screen selection.
