Can anyone tell if this calculations are correct?

LASER Circuit
Resistor Calc

Vt = 5,0 V
Vb = 5,0 V
Vg = 3,0 V
Vr = 3,2 V

It = 240 mA
Ib = 30 mA
Ig = 180 mA
Ir = 30 mA

Rb = 0,00 ohm 0
Rg = 11,11 ohm 11,66666667
Rr = 60,00 ohm 63


I want to make a circuit to deliver voltages to my lasers. Are these resistors value correct? Main Power supply is 5V

Im not exactly sure what u want to do, but to get rid of 2 Volts at 180mA and 1,8V at 30mA I got the same values.

I hope you are going to power your drivers, and not your laser diodes though...

Thanks. Im connecting to drivers ^^
