Hi All,
I am doing the experiment with photodiode and laser light.
The laser source I used is 4.5mW infrared laser with OPV382 and the PD used is
SFH206 with 0.6A/W intensity. I put the the laser source and the PD at 10cm apart. Then 1ohm series resistor is put at PD circut to measure the current.
The current measured is only 10uA.
My question is
(1) does that 10uA current make sense? I am expecting minimum 100uA with that light source and that distance.
(2) How can I improve the current output at PD?
Thanks,
Thomas
