Modulation for 5V/12V Version
Modulation
The laser has two AND-wired modulation input channels, Uanalog and UTTL.
Connecting analog voltage
The input for analog modulation allows applying an analog voltage Uanalog in a range from 0 V to 2.5 V) which allows a linear control of the laser output power from approximately zero up to the maximum power given by the potentiometer setting.
Timing diagram
The laser is OFF in case of an open modulation input. If only one modulation input channel is used, the other has to be set to +5 V.
The voltage Uanalog at analog modulation input linearly controles the laser output power between ≤1 % and 100 % of the optical power set with the potentiometer.
