    Driving 10 (5mW, red) laser diodes

    Hi! I need to use 10 laser diodes, here's the specs: Laser Power 150mW Size ·6-10.5 Spot mode Point-like spot, Continuous output Laser wavelength 650nm(red) Power <5mw Supply Voltage 50 VDC (maybe max rating??) Current <40mA First of all, i made this calculation: one diode needs 150 mW. If i...
