\$\begingroup\$

if it is possible can you let me know the way to get the radiated power of a UV-LED using the output data from the "Ocean optics- Maya pro 2000" spectrometer, or the calculations needed to calculate it from that data.

in the data sheet of the UV-LED the radiated power is from 2mW(min) to 6mW(max) at 40mA current, i uploaded a screenshot for the spectrometer data.

thanks in advance.

  • \$\begingroup\$ well, what is the unit of "power"? What do you get in data? What is missing to convert one to the other? This is pure logical thinking! \$\endgroup\$ – Marcus Müller Oct 7 '20 at 9:30
  • \$\begingroup\$ @MarcusMüller hello sir, i take the second last unit from the the table "uWatt/cm2" and i convert it to mWatt/cm2, in this case 1.36E4 X E-6 to get 13.6mWatt, but i am not sure if i am correct or not. \$\endgroup\$ – KamelK Oct 7 '20 at 9:39
  • \$\begingroup\$ ... how do you do that conversion? (also, you haven't answered "what is missing to convert one to the other", and that's where the trick lies!) \$\endgroup\$ – Marcus Müller Oct 7 '20 at 9:51
  • \$\begingroup\$ @MarcusMüller i was trying to convert the micro watt/cm2 to milli watt/cm2, i don't know if i am right and what is missing to convert, if you can explain it to me i would be grateful sir \$\endgroup\$ – KamelK Oct 7 '20 at 9:55

    \$\begingroup\$ but that's not the unit of power, that's the unit of area power density. You need to be 100% clear what you need, and the math will come to you. \$\endgroup\$ – Marcus Müller Oct 7 '20 at 10:07
