3)What if sample is liquid in glass bottle? would that glass interfere with laser and liquid sample?
4)What kind of power needed for the laser ?50mW, 100mW?
Re: Pi controlled Laser system.
For control and data acquisition and display on a project like that, look at http://experix.sourceforge.net. My unfinished laser modulation and photon counting project is at http://sourceforge.net/projects/experix ... pld-stuff/.
