(a) For the complete list of specifications, please see the manual.
(b) Maximum exposure times of 1 h at 10 W, 60 s at 30 W, and 10 s at 70 W optical power are recommended to avoid overheating of the sensor.
(c) For continuous wave (CW) sources, this value is equivalent to the peak power density, while for pulsed laser sources this value is calculated from the time-averaged power and beam profile.
