Measuring the Total Energy Exposure
For pyroelectric heads, the StarLab application has the ability to sum the total
energy of a number of pulses over a given time period or number of pulses. This
returns the total energy exposure over the selected period. For example, if the
laser is pulsing at 30 times per second, at 1mJ per pulse, and you measure the
exposure over 20 seconds, then the total exposure is 30 x 1 x 20 = 600mJ.

returns the total energy exposure over the selected period. For example, if the
laser is pulsing at 30 times per second, at 1mJ per pulse, and you measure the
exposure over 20 seconds, then the total exposure is 30 x 1 x 20 = 600mJ.
Note: The maximum exposure measurement time is one hour.
Note: StarLab software version 1.00 does not support exposure with the
Pulsar or Quasar devices.
To measure the total exposure:
1. Click the right mouse button and select Exposure from the pop-up menu.
