Option Description
Laser 1 Delay The amount of time (in microseconds) allotted to the primary pulse laser to
charge its flash lamps before firing. Refer to Big Sky Laser’s specification for the
optimal setting.
Dual Pulse Indicates whether or not a secondary pulse laser will be implemented in the
scan.
Laser 2 Delay The amount of time (in microseconds) allotted to the secondary pulse laser
before it fires. This number is plotted from the same zero point as the Laser 1
Delay, allowing this laser to be fired before or after Laser 1.
Set button Calculates the Q-Switch Zero point from the Laser 1 and Laser 2 Delay settings.
The spectrometer’s internal clock operates on .41667 µs pulses and all time-
based events occur at a multiple of that value. For this reason, the values
entered for Laser 1 and Laser 2 Delay will be reformatted to display the actual
time interpreted by the spectrometer.
Orig Integration Start
Delay Displays the last saved value of the Integration Start Delay (in microseconds).
