A/W
Calculation Result
Estimated Photocurrent
5.000 µA
Optical Power: 10.000 µW
Responsivity: 0.5 A/W
Formula: I = P × R
Engineering Note
Photodiode responsivity depends strongly on wavelength and detector material. Use the responsivity specified in the detector datasheet at the actual measurement wavelength for accurate calculations.
