1 Triggering with external electric pulse generator; generator is not included in delivery set.
2 Generation of periodical laser pulses using PC, step 0.01 kHz. Average energy may be changed by software from 20 up to maximum value
(200 + 15% is guaranteed in the range of 0.01-1 kHz, if >1 kHz the max. energy may be less).
3 Generation of periodical laser pulses at 1 kHz rep. rate; external generator and/or PC are not needed.
4 Sync Out signal is generated by pulse of laser light.
5 Without AC/DC adapter AS-120P-12 (12 VDC).
